Age

6-7.

Materials

  • Bbead frame
  • Small form

Preparation


Presentation

  1. To isolate the difficulty of decomposing the multiplicand, we begin with a static multiplication.
  2. From then on the child will work with dynamic problems.
  3. 2321
    x 3
    Write the problem on the left side of the form.
  4. The first thing we must do is to decompose the multiplicand.
  5. "There are how many units?" 1, write 1 on the right side under units.
  6. All of this we must multiply by 3.
  7. On the bead frame, perform the multiplication.
  8. 1 x 3 = 3, move forward three units beads.
  9. 2 x 3=6, but 6 what? 6 tens! Move forward 6 ten beads, etc. (By this time the child should have memorized the combinations and should bring forward the product of the small multiplication)
  10. Read the product and record it on the left side of the form.
  11. Try a dynamic multiplication
  12. 2463
    x 4
    Decompose the multiplicand in the same way as before.
  13. Perform the multiplication 3 x 4 = 12, 12 is 2 units and 1 ten...6 x 4 = 24, 24 what? 24 tens 4 tens and 2 hundreds, etc.
  14. Read the product on the frame and record it.

Control Of Error


Points Of Interest


Purpose

  • To help the child understand the importance of the position of each digit.

Variation

  1. Try performing any one of these multiplications out of order, i.e. 6 x 4 = 24 tens, 2 x 4 = 8 thousands, 3 x 4 = 12 units and 4 x 4 = 16 hundreds. The product is still the same.
