The class solves word problems related to unit rates by identifying the quantity, the units used, and then writing an equation. They practice converting between units using multiplication and division at the right time.

Recipies are a natural medium for using fractions in real-world problems. This delicious activity has learners adapting the ingredients for coconut and chocolate chip macaroons, a Passover treat, for fewer and more cookies than the...

Can you add variables if you don't know their value? Using an empty number line, scholars first locate the position of the difference, sum, product, and quotient of two unknown integers. Later problems mix operations as well as add...

Third graders explore math functions by completing problem solving activities. In this division instructional activity, 3rd graders utilize the division strategies acquired earlier to divide multiple digit numbers by 4's. Students...

Hooray for chocolate chip cookies! Ask your mathematicians to triple a chocolate chip cookie recipe and then reduce the recipe by one-fourth. Your class may need two days to complete, tripling the recipe the first day and reducing the...

Students investigate unit conversion.  In this unit conversion lesson, students will build models of square and cubic centimeters using grid paper and generate formula tables for converting units of area and volume.  The tables...

Students interpret a variety of motion graphs. In this physics lesson, students calculate the speed and acceleration of objects using numerical data from graphs. They apply what they have learned to solve real world problems.

Operating a vehicle remotely can be difficult, especially when the vehicle is on another planet. Young engineers get a feel for some of the real-world challenges as they work to program their rovers (blindfolded group members)...

Understanding how to multiply a whole number by a fraction is the key concept. Young mathematicians create a visual model of this real-world example and find the solution. Extensions are possible for making this an even richer activity....

Creating equations with one variable  to solve real-world-type problems is a key skill any algebra learner needs to master. Here the focus is on realizing that one can write the equation in different ways depending upon how one...

In order to create some tasty fudge, learners must adapt a recipe. Using a recipe for fudge, ingredients must be correctly converted using fractions. If one fraction is incorrect, the fudge will reveal it! Although you will only make one...
