Math Skill/Concept: Grouping by ones, tens and hundreds by drawing pictures that represent concrete materials.
Prerequsite Skills:
One to one correspondence
Counting by ones up to one hundred
Understanding of one, ten, hundred
Experience grouping ones, tens, and hundreds using concrete objects
Learning Objectives:
1) Given a number, draw and count groups of ten.
Important Ideas for Implementation:
1) Only teach students to draw and count groups of ten after students have demonostrated mastery of performing these skills using concrete objects. (See the Concrete Level Instructional Plan).
2) Explicitly link concrete objects to drawings.
3) Teach students an easy way to draw representations (e.g. horizontal line for one, a long vertical line for ten, a square box for hundred.)
4) Emphasize using appropriate place value language (e.g. two tens, four ones).
5) This teaching plan outlines the steps to use when teaching students how to group objects by tens.The same sequence of steps as outlined in this plan should be followed for teaching grouping by hundreds.
