Presentation: Matching the Red Rods with the Red and Blue Rods


1.Set of red rods

2.Set of red and blue rods


Mastery of gradation of red rods.

 Control of error:

Visual and tactile: lengths of pairs of rods must mach.

Transition from sensory area into Math.
 Point of interest:

Making the match.
 1.Invite the child to look at the environment and say " Do you see any materials that look like the red rods?"

2.Define what we are going to do, such as "we are going to match the rods."

3.Teacher chooses a red rod and separates it from the group and lets the child feel how long the rod is.

4.Let the child go to the Red and Blue Rods and find one rod as long as the one the teacher just showed.

5.The child carries the rod back and checks by himself.

6.Let the child move the matching pair to another empty rug.

7.Continue doing the same activity until all rods are matching.


1.Put set away.

2.Grade Red and Blue Rods.

3.Grade pairs.

  1. Thank you for posting this! Was trying to figure out how to make our number rods and red rods. We have an old Jenga game I think we'll use and keep the pieces separate! Thanks for the idea!
