One to One Correspondance: Representational Level

More Teaching Plans on this topic: Concrete

Introduction

Name of Math Skill/Concept: Identify and make groups that show one to one correspondence by drawing pictures that represent concrete materials.

Prerequisite Skills:

• Identifying and making groups that show one to one correspondence using concrete objects.

Although counting is not a necessary skill to be able to match items one to one, these teaching plans do contain several counting activities. If a student cannot count items up to 10, it is recommended that the teacher provide additional scaffolding during these activities. If students have difficulty with writing numerals, provide them with number cards.

Learning Objectives:

1) Identify groups that show one to one correspondence using groups of concrete items and groups of representations of these items.

2) Identify groups that show one to one correspondence using representations of objects.

3) Identify groups that do not show one to one correspondence using representations of objects.

4) Make two groups that show one-to-one correspondence using representations of concrete objects.

Important Ideas for Implementation:

1) Only teach students to identify and create groups that are matched one to one using drawings and other representations after students have demonstrated mastery of performing these skills using concrete objects (See the Concrete Level Instructional Plan).

2) Explicitly link concrete objects to their representations.

3) Teach students an easy way to draw representations of concrete objects (e.g. crayon dots).

4) Color code similar characteristics of numerals (e.g. straight lines of 1, 4, 7).

5) Point out distinguishing characteristics between numerals (flat head seven, skinny one).
