When is the distance formula not accurate? Referencing a map of the school, pairs determine the walking distance between two locations. Creating coordinates for each location, pupils determine the distance between the two points and...

Take mathematics to the hoop! Pairs first measure the linear distances on a basketball court. Using those measurements, they determine the scale lengths to create a scaled model. To finish the activity, learners create models of the...

A soccer-themed interactive challenges mathematicians to solve five questions involving percent equations. Question types include multiple-choice, fill in the blank, true or false and a discussion. A color-coded stadium with movable...

Mathematicians solve six multiple-choice and true or false questions using their knowledge of estimation and multiplying decimals. The interactive provides a garden-themed tool that creates a visual aid of three watering cans to assist...

An interactive challenges mathematicians to round large numbers with help from a large scale that measures the weight of a blue whale. The practie's five questions include multiple-choice, fill-in-the-blank, true or false, and an open...

A six-question interactive tasks scholars with adding binary numbers one through eight. A tool acts as a visual aid to showcase the patterns made when working with base—2, digits zero and one. Question types include fill in the blank,...

Rate the resource as a perfect 10. Pupils use an interactive to help add and subtract numbers. They first explore how to express whole numbers using hundreds, tens, and ones, then explore how to add whole numbers by combining to make...

Here's an interactive that will be a great match for math lesson plans. Young mathematicians use an interactive game to match fractions represented numerically and as fraction models. One game assesses fractions only, while the other...

What makes fractions equivalent? Learners first use an interactive that shows equivalent fractions with fraction models and number lines. They then play a game where they must match sets of equivalent fractions with different denominators.

Mix up math lessons by incorporating an interactive. An educational interactive teaches users about mixed numbers. They first see how to convert between mixed numbers and fraction models. After completing the instruction, they play a...

There's nothing improper in learning about fractions. Scholars apply an interactive to explore models for proper and improper fractions. They then answer a set of questions in a game that requires building models for given fractions and...

Bank on your ability to write equivalent expressions. Scholars use an interactive to create expressions using coins. They then convert these to algebraic expressions and figure out how to evaluate them. A game with various difficulty...

Solving equations in two variables can't be that much harder than solving equations in one variable. Using a balance interactive, scholars solve equations in two variables. They apply inverse operations by adding -x, -y, or -1 as...

Find the right balance between concrete and abstract thinking. After using interactive balances to explore inverse operations, learners solve multi-step equations with variables on both sides. Of course, they can still use the...

Not all interactives are made equal. Scholars use an interactive balance to explore the concept of equality. They place different objects on balances to determine the number of each object needed to balance the scale.

Build on knowledge of fractions to build fractions. Pupils use interactives that require building fraction models for given fractions or mixed numbers and identifying fractions or mixed numbers for given models. A lab area lets users...

Three interactives times three difficulty levels equals nine possible games. Scholars play a online game that requires finding products, determining missing factors, and finding quotients. Multiplication tables are available to help...

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...

Expand the pupils knowledge of using area models to algebra. The interactive allows learners to use the same procedure of getting partial products when multiplying multi-digit numbers to multiplying polynomials. Scholars see how the...

Develop a solid understanding of multiplication. The interactive provides opportunities for learners to continue building a deep understanding of multiplication. Pupils use the application to find the product of two numbers and find...

Provide two views of multiplication. The introduction to an area model application has two modes. One mode shows the area of simple multiplication up to 12 by 12. The second mode shows how area models can be partitioned leading to the...

All that matters is the tiles. Pupils use the interactive to investigate the relationship between area and perimeter using tiles. The interactive has an explore and a game mode to accommodate different steps in learning. The game mode...

Take a second look. Form B of the AP® Calculus BC free-response questions allow pupils and teachers to see another set of items. The six questions expand the set of items from the 2011 free-response questions. Form B items include a...

Keep moving along a curve. Two items in the set of released free-response questions from the 2010 AP® Calculus BC exam involve movement along a graph. One involves particle motion along a polar curve while the other uses a squirrel...
