View source for Small Bead Frame: Multiplication with a One-Digit Multiplier

=== Age  ===

6-7.<br>

=== Materials  ===

*Bbead frame
*Small form<br>

=== Preparation  ===

<br>

=== Presentation  ===

#To isolate the difficulty of decomposing the multiplicand, we begin with a static multiplication. 
#From then on the child will work with dynamic problems.
#2321<br>x 3<br>Write the problem on the left side of the form. 
#The first thing we must do is to decompose the multiplicand. 
#"There are how many units?" 1, write 1 on the right side under units.
#All of this we must multiply by 3.
#On the bead frame, perform the multiplication.
#1 x 3 = 3, move forward three units beads.
#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)
#Read the product and record it on the left side of the form.
#Try a dynamic multiplication
#2463<br>x 4<br>Decompose the multiplicand in the same way as before. 
#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. 
#Read the product on the frame and record it.<br>

=== Purpose  ===

*To help the child understand&nbsp;the importance of the position of each digit.<br>

=== Variation  ===

#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.<br>
