We finished 7 X 9 = Trouble ! and the children were excited to start the multiplication monster tournament! So, I posed a problem " How can we figure out how many cubes are in the basket?" I watched as the students began counting the cubes 1 at a time. This went on for a bit and grew challenging as they tried to recall what number was next counting by 1s 1,2,3,4,5,6,7.... I explained they were skip counting by 1s or adding 1+1+1+1 etc. The line of single cubes was getting very long! A student recalled the 'DVD' video we watched where a man was trying to solve his similar problem of counting his 200 + DVDs. They became excited as they recalled the 'short cut' the man figured out when he too switched from counting by 1s & began grouping them in 10s and skip counting. They were eager to try. We passed out large handfuls of cubes to each child and they began to make bundles or groups of 10s. We then combined our tens , made new 10s with left overs and skip counted by 10s. We added the few left over ones to figure out there was 194 cubes in the basket. A child said it was like counting dimes and pennies. This teacher was happy with all the connections! | |
