Bring your young mathematicians into the fold. Scholars conduct an activity folding paper to see the relationship between the number of folds and the number of resulting layers in the 23rd installment of a 36-part module. The results of...

It won't take young mathematicians long to learn how to measure length with this fun, hands-on activity. Working in pairs, children use Unifix® or snap cubes to measure and record the lengths of different classroom objects. To extend the...

Geometric shapes make great visual models for introducing young mathematicians to the concept of fractions. Looking at a series of four circles, students are asked to determine whether or not one half of each circle is shaded. To support...

Geometry is everywhere, and I mean everywhere! Those skillful mathematicians discuss shapes and then come up with a well-researched list of shapes seen in everyday applications. They put their knowledge of shapes to work as each small...

Middle schoolers choose a mathematician or scientist born on the same day as the student and research them. They create a cube or tetrahedron and place required information on the sides (such as birth year, death yr., greatest...

Your algebra learners build a quadratic function in this task of counting the blocks used to build objects. The arithmetic sequence that shows up brings up a shortcut to the long addition using the Gauss Method. Eventually, learners...

Visual models are excellent teaching tools when explaining equivalent fractions. Looking at a rectangle cut into twelfths, learners first identify the shaded fraction, and then explain whether the fraction is equal to one-fourth....

Seventh graders become familiar with the history and times which influenced a featured mathematician each month. Through Internet research, they gather information about a different mathematician each month. Students solve mathematical...
