Topic Description:
Naming basic 2-D shapes; circle, triangle, square, and rectangle. Identifying some of the characteristics (corners and sides) of 2-D shapes. Making patterns and finding missing items in pattern sequences.

Learning Targets:
• I can show a circle, rectangle square and triangle.
• I can tell the difference between a circle, a rectangle, a square and a triangle by looking at the corners and sides.
• I can see several kinds of patterns
• I can make and find missing items in patterns

Classroom Resources
• Multi-link Cubes
• Attribute blocks
• Geometric blocks or pattern blocks
• Pattern task cards
• Tracing shapes
• Online digital pattern blocks
• Bookmaking materials (paper, scissors, crayon, glue, etc.)

Matholia Tools
• Multi-Link Cubes Tool
• Shape Explorer Tool

Matholia Resources
• Practice modules for the section

Suggested Teaching Sequence
1. Practice sorting objects according to attributes such as small/large, color, shape, sickness, round/not round, etc.
2. Name the four shapes; square, rectangle, circle, triangle
3. Use attribute blocks to count the corners and sides of each kind of shape
4. Discuss the differences between a square and a rectangle
5. Find the four basic shapes in everyday objects in the classroom and school
6. Make basic patterns (AB, AAB, ABB) using the 4 basic shapes together
7. Have children explore, build and manipulate patterns with other objects

Group Practice Ideas
• Sort together: objects, children, blocks, materials, clothing, etc.
• Draw the four shapes together, making note of corners and sides
• Write the names of shapes, read children’s literature about the shapes
• Develop a class shape chart showing the shapes and sorting them by attributes
• Go on a shape safari, where children find the basic shapes in the classroom and in the school
• Make patterns of the children in the classroom (boy-girl, girl-girl-boy) etc.
• Make a book of shapes that shows their attributes
• Make a classroom book of patterns using photographs of the children in the class Independent Practice Ideas Classroom Resources
• Sorting attribute blocks independently into groups using sides, corners and size
• Cutting and pasting activities making the basic shapes
• Using geoboards to build the basic shapes
• Adding patterns shown on pattern block cards
• Adding add on the next three items in a pattern

Review and Assessment
• Matholia review done as a whole group or small group at a center
• Written assessment. Do students understand:
• That shapes can be sorted into groups
• The names of the four basic shapes
• Drawing the three basic shapes
• Making patterns
• Adding on to or finding missing pieces of patterns

Extensions
Name each pattern made (AB, AAB, etc), Identify the part of the pattern that repeats (the pattern unit).
