Math Matters: NOVEMBER 28, 2011

Dear Families,
For the next 2 weeks we will be working on shapes and solid figures. During this unit we will collecting shapes for a shape museum. Please help your child collect containers around the house that could be brought in for our studies. Examples are cereal boxes, plastic cups, paper tubes, etc. Glass and opened metal cans are not allowed! Thank you!

Math I cans for Topic 11: Geometry

Lesson 11.1 Flat Surfaces, Vertices, and Edges (MA-EP-1.1.3.a, 1.1.2)

1) I can identify and draw solid figures by their faces or flat surfaces, edges, and vertices.

Lesson 11.2 Identifying Plane Shapes That Make Up Flat Surfaces of 3-D Shapes (MA-EP-1.1.3.a, 1.1.2)

1) I can tell which plane shapes are on the flat surfaces of solid figures.

2) I can tell how many faces a solid figure has.

3) I can tell how many edges a solid figure has.

4) I can tell how many vertices a solid figure has.

Lesson 11.3 Making New Shapes

1) I can recognize and name trapezoids, parallelograms, and hexagons.

2) I can put shapes together to make new shapes.

3) I can tell the number of sides and vertices in a trapezoid, parallelogram, and hexagon.

Lesson 11.4 Cutting Shapes Apart

I can cut shapes apart to make new shapes.

Lesson 11.5 Congruence

1) I can find, tell about, and create shapes that are congruent.

2) I can tell the word congruent means shapes that are the same size and shape and will fit on top of each other.

Lesson 11.6 Ways to Move Shapes

1) I can tell what these words mean:

a. Translate-Sliding a shape

b. Reflection-Flipping a shape over

c. Rotation-Turning a shape

2) I can tell when to slide, flip, or turn a shape to make it fit a pattern or solve a puzzle or problem.

Lesson 11.7 Symmetry

1) I can tell someone that a line of symmetry divides shapes into 2 equal parts. Some shapes have only 1 or 2 lines of symmetry and others have more.

2) I can draw lines in shapes to tell if they have symmetry.

Lesson 11.8 Problem Solving: Using Reasoning

1) I can use clues to solve riddles about plane shapes and 3-d shapes.
