Mathematics - 3rd Grade

• Hammer Time!
  Students will predict, observe, and compare what happens when a force is applied to an object.
• Math 3 - Act. 14: Tetrominoes Cover-Up
  
• May the Force Be With You
  The hands-on activities described in this lesson will help students better understand the effects of force on an object.
• Mr. Bo Jangle, What's Your Angle?
  Activities help students identify angles found in the real world and classify and draw them.
• Nets
  Students will design and create patterns from grid paper to make boxes or cubes.
• Patterns Around Us
  Students will identify and record patterns that they can find in and outside of the classroom.
• The Earth Is Flat
  This lesson Standard will help students understand that the shape of Earth and the moon are spherical and that Earth rotates on its axis to produce the appearance of the sun and the moon moving through the sky.
• The Pasture and the Fence
  Students will use tiles and grid paper to draw rectangles and then record the perimeter and area of each.
• Try This Triangle Out For Size
  Three different activities reinforce the student's understanding of triangles.

• Properties of Parallelograms and Rectangles
  Dynamic geometry software provides an environment in which students can explore geometric relationships and make and test conjectures. In this example, properties of rectangles and parallelograms are examined. The emphasis is on identifying what distinguishes a rectangle from a more general parallelogram.
• Shapes at Work
  Students record shapes that they find around them, identifying those that can be used to solve practical problems and build larger structures. Students will explore the uses of various shapes and record their findings in a science journal.
• What's In a Shape?
  The purpose of this lesson is to explore characteristics of shapes by making and using tangram sets; to discover how the tangram pieces are related to one another; and to determine how many different combinations of the triangles, squares, and parallelograms in tangram sets can make a given shape.
