Second graders engage in a lesson which focuses on adding two-digit numbers and the regrouping process. They identify when the regrouping process is necessary and make appropriate "trades" to complete an addition problem.

In this estimation worksheet, students read a word problem about the Lincoln Memorial and then answer 4 fill in the blank questions where they decide whether they need to use an exact number or an estimate to answer each question.

In this addition worksheet, students compete 12 problems, adding one 2-digit number to another. A reference web site is given for additional activities.

For this addition worksheet, students complete 12 problems, adding one 2-digit number to another. A reference web site is given for additional activities.

There is more than one way to add mixed numbers. This worksheet asks 5th graders to find and record two ways. The purpose is to help pupils realize there are different ways to reach a common solution in math. The two most common ways are...

Support math instruction at home with a helpful reference sheet designed for parents. Three pages cover the subject of addition with written details and labeled pictures. 

Middle schoolers identify proper, improper fractions, and mixed numbers.  They reduce fractions to their lowest terms. They add and subtract fractions with different denominators, and multiply and divide fractions, as well as...

Kids are challenged to make a human number line. They line up, holding numbers from -10 to 10. They then add and subtract both positive and negative numbers, using themselves as the numbers on the number line. This is a great way to...

Being able to recognize number bonds that make 10 is a great way to help learners add 3 digits together. First they make 10 by adding two numbers together, then they assess 3 digit addition sentences, where they make 10 first then add-on...

It all adds up to one. Pupils solve several items that involve finding sums of fractions in relationship to a whole. The assessment task uses fractions with unlike denominators to determine the amount of a tank of gas and the amount of...

Complete these images with values one less and one more; young mathematicians fill in bunches of flowers, starting at a middle number and working their way to the right by addition and to the left by subtraction. For each flower they...

Writing equations from images helps young mathematicians grasp addition, especially when they get to look at cute animals as they do it. There are six number sentences here, each illustrated with a set of animals corresponding to...

Investigate the relationship between addition and subtraction as scholars fill in these number sentences, each of which is missing a symbol. Is it a subtraction or addition equation? There are 20 of these to start, all written...

In this simple worksheet, learners add and subtract positive and negative integers. Mathematicians plot the problem on a number line beside each of the 24 problems. You might want to white out the answers at the bottom of each page and...

Learners divide a poster board so everyone gets the same amount of area to decorate. Youngsters talk about the different ways to divide a rectangle. They measure their lines to make sure that each piece is equal and then decorate their...

Investigate equivalent fractions with your class. They compare and order fractions. Then they work cooperatively in groups to experiment and problem solve with fractions using a game format. Multiple resources are provided.

Number sequences make for great challenges that stimulate pattern recognition, algebraic reasoning, and number sense. This slide-show includes eleven number sequences for learners to work through, an explanation of what number sequences...

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...

Excite the class with a mathematical trick, a calculator, and a good number sense. They use the directions provided on each slide to make a list of numbers, use their calculator to divide, and find the golden mean. A little history on...

These dragons work as math machines as scholars multiply numbers using given functions, which remain the same for these: double it. Using an example as their guide, learners double three whole numbers, none of which exceed 11, for each...

Work with the class to investigate the concept of dividing decimals. They will use a variety of problem-solving skills in order to practice the operation of division. The teacher can use the dialogue to guide learners through the various...

Give kids a few strategies to help them become amazing problem solvers. This presentation is intended to be used over a two-day period and presents several techniques or ways to solve word problems or multiplication problems by...

How many now? Math beginners will benefit from this introduction to addition which doesn't even include addition symbols. They read number sentences in word form; however the numbers are in numeric form (for example, "1 and 2 more...

Brrrr it's cold in Alaska! When given the temperatures of Anchorage and Miami in the winter, your mathematicians will calculate how much warmer it is in Miami. Answer key provides two different solution choices. Great as a warm-up for...
