We got a whole lot accomplished in August. All grade levels learned the routines and procedures of Math Lab. All grade levels have done some sort of problem solving. All grades except for kindergarten have been introduced and have started using Bar Model Drawing for problem solving which is a 7 step method we have adopted from Singapore. Grades 3rd-5th have been introduced to and have started using a graphic organizer that helps them write a constructed response in math. Kindergarten and 1st graders have been busy moving to music as they practice math skills.
Thanks to the generosity of the parents and foundation, we have been able to play several games in Math Lab including What's My Number, 24 Game, and Figuro. We also have a new rug in the math lab thanks to the PMES Foundation.
Now that we have had time to get everything in place, we can really dig in deep to Mental Math strategies. Here are the strategies we are currently working on:
Kindergarten: Subitizing- the skill of being able to determine how many of something without having to count each individual item
First Grade: Modeling numbers in a variety of ways
Second Grade: Counting on when adding 1-4 to a given number (first addend will vary depending on individual needs)
Third Grade: Counting back on a chart when taking away 1-4 (Subtrahend will vary depending on level of individual students)
Fourth Grade: Using 10 facts when multiplying by 5 (Examples from 3 different levels: 4X10=40 so I know 4X5=20, 20X10=200 so I know 20X5=100, 246X10=2,460 so I know 246X5=1,230)
Fifth Grade: Using 10 facts when dividing by 5 (Examples from 3 different levels: 20/10=2 so 20/5=4, 160/10=16 so 160/5=32, 3,200/10=320 so 3,200/5=640)
