This dot card image was shared by jo boaler at a recent workshop. because there are more than 5 dots, most people will conceptually subitize by making multiple “groups” of dots often forming some sort of visual pattern in the mind. give this one a shot. consider using these images to prompt number talks around conceptual subitizing and. Subitizing is the ability to know the number of objects in a small collection without counting. when subitizing, students form mental image of number patterns, which in turn, helps students learn to count. when practicing subitizing with children, use dot cards or objects, but not manipulatives. when using.

5 and 10 frames are powerful tools for building those all important benchmarks of 5 and 10, and they should also be part of your subitizing routines. they can be used in much the same way as random pattern dot cards. a great resource for using 10 frames in your classroom is it makes sense!: using ten frames to build number sense. Maybe you see 3 2 2 = 7. i have been using dot cards for many years with k 2 students as part of my number talks routine. i’d like to share some ways to follow this routine using both ten frame dot cards and random dot cards. these are also easy to use via distance learning situations. if you haven’t tried this before, you are in for a. So two dot cards that both show 7 dots would be a match. you could also use the blank cards to write numerals and kids could match a dot card with the correct numeral. for instance, a dot card with 5 dots would match the number ‘5’ card. for older kids who are ready, you can play “make 10” match. in this game, kids have to find dot card. Cards should have a strong contrast with background. ways to use the cards: show cards and have students say the number without counting. play a matching game. display several cards one of which is a different number than the rest and have players identify which doesn’t fit. use two decks of cards. give each student one and have them select a.

Dot cards. these dot cards are a great way to build on our innate subitizing ability and develop number understanding for 1 10. have kids learn to identify the numbers, then use them to teach making 5 and making 10. you can also print 2 sets to practice doubling numbers!. Ten frames and dot cards can be used to develop students’ subitizing skills, the ability to “instantly see how many.”. this skill plays a fundamental role in the development of students’ understanding of number. two types of subitizing exist. perceptual subitizing is closest to the original definition of subitizing: recognizing a number.
