You may have heard your child mentioning subitizing activities we have been doing in class. Subitizing is "instantly seeing how many" meaning, subitizing is not counting but recognizing common pattern arrangements such as those we may see on a dice or domino. How good can you subitize? The results might surprise you....
not easy eh?
The students has been practicing this, doing games, quizzing one another and just explaining what they see. This is an example of what a student might explain if they were subitizing if they saw this picture for just a few seconds:
They would tell me they see 9, when I ask how they know here are some explanations I have heard from them before:
"I see 3groups of 3 and if you add 3+3+3 that is 9"
"I saw one group of 6 blue dots and one group of 3 red dots and that gives you 9"
"I recognize that pattern, when I see it I know it's 9 because I've seen it before"
This is something that can easily be practiced at home, the students have really enjoyed the games we play in class and as they progress the hope is that the more they can subitize quickly they better their number sense will be if they can instantly see things in groups and be able to clearly explain how they know the answer. Things that can be used at home to practice:
-coins
-dominos
-dice
-cards with dots
-anything you can see in groups!!!
