This week I was able to teach a small group lesson to a pair of girls who were struggling with understanding the procedures for doing lattice multiplication. One of the girls just needed to hear the procedures more slowly and be given time to work through a problem while getting confirmation that she is doing the procedures correctly.
The second girl is very low level in her math understanding. Her strategy for simple multiplication (i.e. 7x8) is counting up on her fingers starting at 1. While making sure she understood the procedures for lattice multiplication and helping her through the multiplication, I made an effort to help her understand some other methods for solving simple multiplication, such as solving 7x8 by splitting it into 5x8 and 2x8. I introduced this method to her because she does pretty well with multiples of 2, 5, and 10. I also introduced the method of solving 7x8 by finding 7x10 then counting backward 2 sets of 7. She responded well to both of these methods and understood how to use both. I did not have enough time see if she was able to take these methods and apply them to other 1 diget multiplication, but the unit 2 summative assessment is on Monday, so I will be able to assess her growth and understanding of multiplication.
