Prerequisites | Long Rods |
Materials | set of Number Rods |
Also called the Red and Blue Rods.
This activity teaches the child the concept of quantities 1 - 10 and their names.
Presentations
First Presentation
- Starting with the shortest rod, carry the rods one at a time to a mat. Lay them all out parallel to each other but in random order as shown.
- Put them in order the same way as was done with the Long Rods.
- Isolate the 1 rod and place a hand on it saying: "One."
- Isolate the 2 rod and count each section: "One, two." Then name the rod: "Two."
- Do the same with the 3 rod. Then do a three period lesson with the first three rods.
Subsequent Presentations
- In later lessons, introduce the other rods in the same way.
Points of Interest
Instruct the child to build the stair (as they did with the red rods), keeping the red end of each rod to the left side of the mat (POI).
Control of Error
- visual - pattern of colored sections
- internal – sense of length acquired through work with red rods
- internal – sense of sequence of numbers acquired through auditory memory.
Variations and Extensions
- Once all are lined up onto rug, slide smallest rod up ‘stair’, demonstrating its size is equal to the difference between each rod next to the other.
Material
This material consists of ten wooden rods, painted alternating red and blue. The shortest rod is 10cm in length, they each increase in length by 10cm up to the longest which is 100cm long. The ends of the rods are 2.5cm square.
Make Your Own
The Number Rods can be made by cutting 1" x 1" boards to the correct length, taping them off, and then painting them.
(A more detailed description of how this was done can be found at A Handmade Childhood.)
