Numbers and Operations Teacher Resources

Add another strategy to the toolboxes of young mathematicians with this elementary math lesson on using number lines to add and subtract fractions.

Learn how to do approximations to find a quotient. Given some large numbers to divide, how can this problem be tackled? It's often a good idea to do an approximation first as this can help to be in the ballpark in finding the solution....

In this pre-algebra worksheet, students round 6 whole numbers to the underlined place. They round to an indicated place value in 6 problems. Students round to the underlined place value in 6 decimal numbers. They round to the given place...

Master composite and prime numbers with this fast-moving game. Using your sword, slice those composite numbers and watch them break up into factors. Slice again if those factors are composite. However, watch out for prime numbers,...

Kindergarteners explore various representations and uses of numbers to develop number sense. They participate in an activity and arrange patterns into groups. Students compare the sets and describe the objects in each set.

In this mathematics worksheet, 1st graders identify various numbers and use counters to illustrate each fact given. Then they complete the math sentences correctly.

Need a unit to teach fractions to fourth graders? Look no further than this well-developed and thorough set of lessons that takes teachers through all steps of planning, implementing, and assessing their lessons. Divided into eight...

Make sure your students' understanding of fractions is on-point using this series of skills practice worksheets. Covering a variety of topics from basic place value and fraction/decimal conversion, to performing all four operations...

Decipher the equations in these addition and subtraction word problems. Two examples at the top of the page guide second graders as they solve the rest of the problems. There is no space to write out the equation, but there is a place to...

Access prior knowledge to practice concepts like order of operations and exponents. Your class can play this game as a daily review or as a warm-up activity when needed. They work in groups of four to complete and correct review problems.

Budding mathematicians investigate how to write number sentences using the Roll-the-Dice tool in "Kid Pix". They correlate the dots on the dice to numbers and then learn to use the addition and equal symbols to write number sentences....

In this operations worksheet, students solve a word problem involving the math operations in order. Students complete 1 complicated higher order thinking problem.

Fifth and sixth graders compare decimals to the place-value structure in the base-ten number system. They represent fractions as parts of unit wholes, as parts of a set, as locations on a number line, and as divisions of whole numbers....

Represent, order, and compare rational numbers in order to practice placing them on a number line. Your class will use appropriate operations, methods, and tools to compute with real numbers. Then they must explain completely and clearly...

Investigate the order of operations! Learners participate in interactive multi-media activities to examine and solve multi-step equations, inequalities. They evaluate formulas and simplify monomials and polynomials.

How do you solve a problem when a symbol or letter is used in place of a missing number? Build algebraic reasoning and problem solving skills with this presentation that explains three methods for finding a missing variable. The guess...

Young scholars solve problems using PEMDAS. In this algebraic equations lesson, students evaluate expressions using real number properties. They play "Math Jeopardy" to reinforce the order of operations.

Numerical expressions contain numbers and mathematical operations. In addition to numerical expressions, algebraic expressions contain not only numbers but also variable(s). Watch this video as the instructor illustrates several examples...

Like the cubs in A Fair Bear to Share, your 2nd grade class will practice adding and subtracting double-digit numbers by grouping, regrouping, and sorting a collection of objects. This requires many resources, but it is well worth the...

Young mathematicians review the basic operations needed for addition and subtraction of fractions. They review the rules for addition and subtraction of fractions with the same denominator, how to change them if the denominators are...

Learners complete a 24 page unit. They solve expressions by plugging in values, and translate words into algebraic equations. Included are: mixed operations, square roots, exponents and negative numbers. This resource provides a good...

Your class can learn all about inverse operations. They will review what inverse operations are, see examples, learn how to use inverse operation to check an answer, write addition and subtraction equations in the inverse, and use the...

Introduce your class to cube roots! You can show them this video, in which an instructor demonstrates how to find the cube root of a perfect cube. While this video is clear and well-made, it is appropriate only for more advanced learners...

In this substitution and evaluation instructional activity, learners solve and complete 22 different problems that include using the substitution method of variables. First, they evaluate each expression for the given variable. Then,...
