Decimal place value is the topic of a Battleship themed-interactive. Scholars answer five questions—multiple-choice and true or false—while referencing a grid that acts as the board game. The practice concludes with a discussion...

Three activities make up an introductory lesson designed to create a strong foundation in comparing fractions to decimals and exploring and building decimal models. Pupils brainstorm and complete a Venn diagram to show how decimals and...

Develop a better understanding of the value of pi. Learners explore the area of a circle using estimation and graph paper. While continuing to estimate the area of the circle using smaller and smaller grids, the number pi emerges. 

It is all about being equivalent. Class members convert between fractions, decimals, and percents. By using visual models, scholars verify their conversions in the 25th portion of a 29-part series.

Test young mathematicians' knowledge with an assessment aligned to California's fifth grade state standards. The exam covers a multitude of concepts including fractions and decimals, positive and negative numbers, measurement; and...

Area works with decimals too. Pupils use the interactive to model multiplication of two decimals using an area model. They see how the decomposed components of the factors obtain partial products and then the complete product. Using area...

What percentage of your class understands percents? Pupils learn the meaning of percents based upon rates per 100 in the 24th instructional activity in a series of 29. They represent percents as fractions, decimals, ratios, and models....

What happens when combining percentage discounts? The last activity in a series of 29 introduces the idea of combining discounts one after another. Pupils wrestle with the claim that to find the total discount, they need to only add...

What if I can no longer justify area by counting squares? Lead a class discussion to find the area of a rectangular region with irrational side lengths. The class continues on with the idea of lower approximations and...

In this exercise, students practice decimal intuition with grids. Students receive immediate feedback and have the opportunity to get hints and try questions repeatedly.

Practice writing decimal numbers shown in grid diagrams. Students receive immediate feedback and have the opportunity to try questions repeatedly, watch a video or receive hints.

Exercise provides practice with writing numbers both as a fraction and a decimal. Immediate feedback is given and hints or a video are available if needed.

Practice these problems to see how decimals and fractions can represent the same number. Students receive immediate feedback and have the opportunity to try questions repeatedly, watch a video or receive hints.
