Learn how to use subitizing cards to help students build conceptual understanding and fact fluency of multiplication. download the cards and see examples of how to use them in class and at home. Learn how to use multiplication subitizing cards to help students develop multiplicative thinking and automatize facts. see a video example of a second grader using subitizing and commutative property strategies.
Let’s take a look at how we can take subitizing to another level to begin developing multiplicative reasoning. this will be done with “quick looks” where we show a card to our students for about 2 seconds. during that time, they will try to figure out how many dots are on the cards. the short time frame ensures that they do not have time. My takeaways: it’s easy to identify which facts she’s comfortable with and has automatized. at 1:15– she demonstrates how she used multiplicative thinking for 6×6. at 2:00 she could use her understanding of the commutative property for multiplication to build fluency. she was quickly is able to recognize that 7×5=35 at 1 minute, but it. Subitizing for multiplication these subitizing cards are designed to be used to build multiplicative reasoning. byusinga“string”ofsubitizingcards. Multiplication subitizing cards (dice) the next set of cards is to move students away from one to one counting.
