Math: algebra


Prepare in advance 18 cubes.
Put 18 cubes next to you. Say today we will see how we can multiply things. Look, we have here 6 cubes (show 6 fingers). Count the cubes by pointing to them. Put the 6 cubes in a row in front of the baby. Say: I want to multiply those cubes by 3, it means I want to have 6 cubes put in 3 rows. Take another 6 cubes and put them right below the first ones. Point to the second row of cubes and count them: 1,2,3,4,5,6. Show 6 fingers. Say: there are two rows now. Let’s make 1 more. Take 6 more cubes and put them in 1 more row all below the first two rows. Count 1,2,3,4,5,6 while putting. Say: let us count our row: 1,2,3. There are 3 rows having 6 cubes each. Now we have to count all of the cubes together. Pointing to the cubes, start counting from the upper left corner, left to right, up to down: 1,2,3,4, … 18! Eighteen. (show 18 fingers, ten and then again 8). 6 multiplied by 3 equal 18! Now repeat the same with towers instead of rows.
