Elementary and middle schoolers participate in an assignment to explore the concept of division and having a remainder. They also practice division problems using decimals and fractions without a remainder.

Students solve word problems and determine quotients of fractions and mixed numbers. They practice multiplying fractions by increasing a recipe found on a food website. In addition, they increase the numbers to feed the whole class a...

Expand on prior knowledge of place value to teach your class how to round whole numbers. This essential skill is explained with the help of a number line before introducing the explicit rules for rounding numbers up and down. Work...

Learning how to visualize is an important step in the growth of young mathematicians. The first video in this two-part series helps learners develop this ability by using visual models to explain multiplication of fractions by whole...

Practice adding whole numbers by combining the amount of fish Alice and Bob catch. As young mathematicians work through each problem, they are asked to find one more plus the amount of fish already caught. They can manipulate the...

As penguins jump off of an iceberg, young mathematicians count the remaining penguins in order to discover the whole number subtraction answer. As they work through the questions, they can manipulate the red dot to add and subtract more...

Estimating whole number multiplication and division is the focus of an interactive that uses a garden plot with moveable points to answer six questions.

This is a cute lesson that kids will be able to relate to. They are shown how to trade tens and regroup when adding and subtracting two digit numbers. The nice thing about this lesson is that it can be personalized to fit your class.

Estimating is an essential skill used in everyday life. This presentation explains how to apply prior knowledge about rounding numbers to estimating sums and differences. Example problems and assessment include large numbers, making this...
