Mathematics is especially useful when it helps you predict, and number patterns are all about prediction. Count forward beginning from a given number within the known sequence (instead of having to begin at 1). When counting objects, say the number names in the standard order, pairing each object with one and only one number name and each number name with one and only one object.

Count to answer "how many?" questions about as many as 20 things arranged in a line, a rectangular array, or a circle, or as many as 10 things in a scattered configuration; given a number from 1-20, count out that many objects.

Classify objects into given categories; count the numbers of objects in each category and sort the categories by count.

Order three objects by length; compare the lengths of two objects indirectly by using a third object. Express the length of an object as a whole number of length units, by laying multiple copies of a shorter object (the length unit) end to end; understand that the length measurement of an object is the number of same-size length units that span it with no gaps or overlaps. Organize, represent, and interpret data with up to three categories; ask and answer questions about the total number of data points, how many in each category, and how many more or less are in one category than in another.

Compose two-dimensional shapes (rectangles, squares, trapezoids, triangles, half-circles, and quarter-circles) or three-dimensional shapes (cubes, right rectangular prisms, right circular cones, and right circular cylinders) to create a composite shape, and compose new shapes from the composite shape.

Partition circles and rectangles into two and four equal shares, describe the shares using the words halves, fourths, and quarters, and use the phrases half of, fourth of, and quarter of.

Measure the length of an object by selecting and using appropriate tools such as rulers, yardsticks, meter sticks, and measuring tapes. Measure the length of an object twice, using length units of different lengths for the two measurements; describe how the two measurements relate to the size of the unit chosen. Measure to determine how much longer one object is than another, expressing the length difference in terms of a standard length unit. Solve word problems involving dollar bills, quarters, dimes, nickels, and pennies, using $ and ? symbols appropriately.

An angle is measured with reference to a circle with its center at the common endpoint of the rays, by considering the fraction of the circular arc between the points where the two rays intersect the circle. An angle that turns through n one-degree angles is said to have an angle measure of n degrees. Draw points, lines, line segments, rays, angles (right, acute, obtuse], and perpendicular and parallel lines. Classify two-dimensional figures based on the presence or absence of parallel or perpendicular lines, or the presence or absence of angles of a specified size. Recognize a line of symmetry for a two-dimensional figure as a line across the figure such that the figure can be folded along the line into matching parts. Use parentheses, brackets, or braces in numerical expressions, and evaluate expressions with these symbols.

Find free number pattern teaching ideas, activities and resources for your primary and secondary classroom. Sometimes it helps to find the differences between each pair of numbers this can often reveal an underlying pattern. Represent a number of objects with a written numeral 0-20 (with 0 representing a count of no objects).

The number of objects is the same regardless of their arrangement or the order in which they were counted. For example, “Can you join these two triangles with full sides touching to make a rectangle? For example, determine the unknown number that makes the equation true in each of the equations 8 + ? In this range, read and write numerals and represent a number of objects with a written numeral.

Show the measurements by making a line plot, where the horizontal scale is marked off in whole-number units. Solve simple put-together, take-apart, and compare problems using information presented in a bar graph. For example, describe a context in which a total number of objects can be expressed as 5 ?7. For example, describe a context in which a number of shares or a number of groups can be expressed as 56 ?8.

For example, determine the unknown number that makes the equation true in each of the equations 8 ? ?

For example, observe that 4 times a number is always even, and explain why 4 times a number can be decomposed into two equal addends.

Solve one- and two-step ""how many more"" and ""how many less"" problems using information presented in scaled bar graphs. Show the data by making a line plot, where the horizontal scale is marked off in appropriate units-whole numbers, halves, or quarters. Find areas of rectilinear figures by decomposing them into non-overlapping rectangles and adding the areas of the non-overlapping parts, applying this technique to solve real world problems.

Represent measurement quantities using diagrams such as number line diagrams that feature a measurement scale. For example, find the width of a rectangular room given the area of the flooring and the length, by viewing the area formula as a multiplication equation with an unknown factor. Solve problems involving addition and subtraction of fractions by using information presented in line plots.

When an angle is decomposed into non-overlapping parts, the angle measure of the whole is the sum of the angle measures of the parts. Use benchmark fractions and number sense of fractions to estimate mentally and assess the reasonableness of answers. Multiply fractional side lengths to find areas of rectangles, and represent fraction products as rectangular areas. Use operations on fractions for this grade to solve problems involving information presented in line plots. Find volumes of solid figures composed of two non-overlapping right rectangular prisms by adding the volumes of the non-overlapping parts, applying this technique to solve real world problems.

For example, if it took 7 hours to mow 4 lawns, then at that rate, how many lawns could be mowed in 35 hours? Use the distributive property to express a sum of two whole numbers 1–100 with a common factor as a multiple of a sum of two whole numbers with no common factor. For example, interpret –3 > –7 as a statement that –3 is located to the right of –7 on a number line oriented from left to right.

Include use of coordinates and absolute value to find distances between points with the same first coordinate or the same second coordinate. Use substitution to determine whether a given number in a specified set makes an equation or inequality true. Analyze the relationship between the dependent and independent variables using graphs and tables, and relate these to the equation. Apply the formulas V = l w h andV = b h to find volumes of right rectangular prisms with fractional edge lengths in the context of solving real-world and mathematical problems. For example, if total cost t is proportional to the number n of items purchased at a constant price p, the relationship between the total cost and the number of items can be expressed as t = pn.

Generate multiple samples (or simulated samples) of the same size to gauge the variation in estimates or predictions. For example, the mean height of players on the basketball team is 10 cm greater than the mean height of players on the soccer team, about twice the variability (mean absolute deviation) on either team; on a dot plot, the separation between the two distributions of heights is noticeable. For example, decide whether the words in a chapter of a seventh-grade science book are generally longer than the words in a chapter of a fourth-grade science book. For example, when rolling a number cube 600 times, predict that a 3 or 6 would be rolled roughly 200 times, but probably not exactly 200 times.

For example, if a student is selected at random from a class, find the probability that Jane will be selected and the probability that a girl will be selected. For example, find the approximate probability that a spinning penny will land heads up or that a tossed paper cup will land open-end down.

For example, use random digits as a simulation tool to approximate the answer to the question: If 40% of donors have type A blood, what is the probability that it will take at least 4 donors to find one with type A blood? Understand informally that every number has a decimal expansion; for rational numbers show that the decimal expansion repeats eventually, and convert a decimal expansion which repeats eventually into a rational number.

For example, estimate the population of the United States as 3 ? 10 8 and the population of the world as 7 ? 10 9 , and determine that the world population is more than 20 times larger. Show which of these possibilities is the case by successively transforming the given equation into simpler forms, until an equivalent equation of the form x = a, a = a, or a = b results (where a and b are different numbers). For example, given coordinates for two pairs of points, determine whether the line through the first pair of points intersects the line through the second pair. The graph of a function is the set of ordered pairs consisting of an input and the corresponding output. For example, given a linear function represented by a table of values and a linear function represented by an algebraic expression, determine which function has the greater rate of change. For example, the function A = s 2 giving the area of a square as a function of its side length is not linear because its graph contains the points (1,1], (2,4) and (3,9], which are not on a straight line.

Determine the rate of change and initial value of the function from a description of a relationship or from two (x, y) values, including reading these from a table or from a graph. Sketch a graph that exhibits the qualitative features of a function that has been described verbally. For example, arrange three copies of the same triangle so that the sum of the three angles appears to form a line, and give an argument in terms of transversals why this is so. For scatter plots that suggest a linear association, informally fit a straight line, and informally assess the model fit by judging the closeness of the data points to the line.

Understand for these examples that decomposing into more equal shares creates smaller shares. Assess the reasonableness of answers using mental computation and estimation strategies including rounding.

For example, draw a bar graph in which each square in the bar graph might represent 5 pets.

Determine whether a given whole number in the range 1-100 is a multiple of a given one-digit number.

For example, given the rule “Add 3” and the starting number 1, generate terms in the resulting sequence and observe that the terms appear to alternate between odd and even numbers.

For example, from a line plot find and interpret the difference in length between the longest and shortest specimens in an insect collection.

Form ordered pairs consisting of corresponding terms from the two patterns, and graph the ordered pairs on a coordinate plane. For example, given different measurements of liquid in identical beakers, find the amount of liquid each beaker would contain if the total amount in all the beakers were redistributed equally. Perform arithmetic operations, including those involving wholenumber exponents, in the conventional order when there are no parentheses to specify a particular order (Order of Operations). Compare an algebraic solution to an arithmetic solution, identifying the sequence of the operations used in each approach. For example, estimate the mean word length in a book by randomly sampling words from the book; predict the winner of a school election based on randomly sampled survey data.

Do the outcomes for the spinning penny appear to be equally likely based on the observed frequencies? For example, compare a distance-time graph to a distance-time equation to determine which of two moving objects has greater speed. For example, 3x + 2y = 5 and 3x + 2y = 6 have no solution because 3x + 2y cannot simultaneously be 5 and 6. Interpret the rate of change and initial value of a linear function in terms of the situation it models, and in terms of its graph or a table of values. If 9 people want to share a 50-pound sack of rice equally by weight, how many pounds of rice should each person get? Understand the connections between proportional relationships, lines, and linear equations. She says Target claimed that was impossible, it could only be scratched off."They told me there was nothing I could do. They say it will provide faster service than calling corporate customer service.It is good consumer practice to check the strip on any gift card.

Mathematics is especially useful when it helps you predict, and number patterns are all about prediction. Count forward beginning from a given number within the known sequence (instead of having to begin at 1). When counting objects, say the number names in the standard order, pairing each object with one and only one number name and each number name with one and only one object.

Count to answer "how many?" questions about as many as 20 things arranged in a line, a rectangular array, or a circle, or as many as 10 things in a scattered configuration; given a number from 1-20, count out that many objects.

For example, estimate the population of the United States as 3 ? 10 8 and the population of the world as 7 ? 10 9 , and determine that the world population is more than 20 times larger. Show which of these possibilities is the case by successively transforming the given equation into simpler forms, until an equivalent equation of the form x = a, a = a, or a = b results (where a and b are different numbers). For example, given coordinates for two pairs of points, determine whether the line through the first pair of points intersects the line through the second pair. The graph of a function is the set of ordered pairs consisting of an input and the corresponding output. For example, given a linear function represented by a table of values and a linear function represented by an algebraic expression, determine which function has the greater rate of change. For example, the function A = s 2 giving the area of a square as a function of its side length is not linear because its graph contains the points (1,1], (2,4) and (3,9], which are not on a straight line.

Determine the rate of change and initial value of the function from a description of a relationship or from two (x, y) values, including reading these from a table or from a graph. Sketch a graph that exhibits the qualitative features of a function that has been described verbally. For example, arrange three copies of the same triangle so that the sum of the three angles appears to form a line, and give an argument in terms of transversals why this is so.

Perform arithmetic operations, including those involving wholenumber exponents, in the conventional order when there are no parentheses to specify a particular order (Order of Operations). Compare an algebraic solution to an arithmetic solution, identifying the sequence of the operations used in each approach. For example, estimate the mean word length in a book by randomly sampling words from the book; predict the winner of a school election based on randomly sampled survey data.

Do the outcomes for the spinning penny appear to be equally likely based on the observed frequencies? For example, compare a distance-time graph to a distance-time equation to determine which of two moving objects has greater speed. For example, 3x + 2y = 5 and 3x + 2y = 6 have no solution because 3x + 2y cannot simultaneously be 5 and 6. Interpret the rate of change and initial value of a linear function in terms of the situation it models, and in terms of its graph or a table of values.
