The students worked in pairs today using the unifix cubes (in groups of 10) to find multiples of 10. If a pair of students had 3 groups of 10 unifix cubes, they would come up to the board and write 3 groups of 10 as well as 3 x 10 =30. Then I would have the groups give away certain groups of 10 to other student pairs and they would find how many groups of 10 they had after the switch. The students did a really wonderful job with their groups of 10 and even found the trick/pattern to multiplying by 10, which is to take the original number and add a zero to it. I have posted some links to 10’s multiplication to the bottom of this post. Continue reading
