Age
6-9.
Materials
- Box of colored bead bars 1-10
- One each of the squares 1-10
Preparation
Presentation
- Directress says to the child; "Let's try to multiply all of the numbers by themselves".
- During this activity the child writes the equations as he goes along.
- He may also draw this on graph paper as he progresses or when he is finished.
- Start with one. directress says: "One taken one time is one".
- Put out one bead.
- Write down 1 x 1 = 1.
- Directress says; "Two taken two times is four."
- Place two 2- bars in a column next to one.
- Write down 2 x 2 = 4.
- Continue in this manner until 10 x 10, resulting in 9 columns in a row.
- If the child doesn't remember a combination he may check Chart I.
- Directress says; "We have multiplied all the numbers by themselves. What have we formed? Squares. Because these are only bars, we can substitute them with the real squares".
- "With one, there is no square because 1 x 1 is just 1".
- Replace the 2 bars of 2 with the 2 square and so one up to 10.
