Second graders create a fact family town to develop the understanding of numbers related in fact families. They learn each family has a big number and two baby numbers. They make triangle shaped houses for their facts.

Students complete a worksheet.  For this fractions lesson, students review their knowledge of fractions, define equivalent fractions, see examples of equivalent fractions and practice making equivalent fractions.

Third graders use pattern blocks of one shape at a time to try to create a similar shape. They compare the perimeter of the new figure with the perimeter of the original shape and look for a pattern. Students use the pattern to predict...

Students explore geometric shapes.  In this kindergarten geometry lesson, students create a fall quilt consisting of three different paper geometric quilt squares that when assembled form a scarecrow, a pumpkin, and a crow. ...

Students investigate the interior angles of a triangle. For this geometry lesson, students create the formula to calculate the angles inside a triangle. They observe the total sum of a triangles angle on the navigator.

Students explore the ways Geometry can help solve probability problems. Students describe platonic solids and practice calculating probability using an online resource. They construct dice with various numbers of sides to demonstrate...

Students create a ruler for the purpose of measurement using the standard and metric systems. The rulers are of different lengths and are compared to one another. Then students make conversions of different lengths using both systems of...

Students determine the density of different substances. In this physical science lesson plan, students rank them according to their density. They discover the relationship between volume and density.

Explore division by modeling problems and grouping with manipulatives. This video focuses on dividing whole numbers by unit fractions and modeling the problems with unit blocks.

Visualize solutions to multi-digit division problems by modeling them with virtual manipulatives. This interactive exercise focuses on calculating quotients by working with area models and visualizing the distributive property of division.

The lesson will help students develop an initial understanding of division and clarify how the four operations of addition, subtraction, multiplication, and division relate to and are separate from each other. The lesson begins with a...

This resource consists of a detailed, hands-on lesson plan for dividing fractions using manipulatives such as fraction bars.

This S.O.S. tutorial gives students a basic review of simple fractions. Follow the tutorial to refresh your skills involving simple fraction manipulations. Each section contains problems with links to the answers.

This tutorial on signed numbers features lesson plans, practice pages, examples, application problems, and interactive work. Teacher resources include overhead manipulatives, card games, a Bingo game, and graphing calculator downloads.

Cyberchase video clip in which Bianca, who is babysitting, must take two girls trick-or-treating on Halloween. Students are asked to determine how the two girls will split their candy equally between the three of them. [3:27]
