Using Ten Frames and Dot Cards
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 without using other mathematical processes. For example, a child as young as two might “see 3” without using any learned mathematical knowledge.
Conceptual subitizing is being used when a person sees an eight dot domino and “just knows” the total number. The number pattern is recognized as a composite of parts and as a whole. The domino is seen as being composed of two groups of four and as “one eight”.
Enlarged dot cards can be used during mental math sessions to prompt mental images of numbers and different mental strategies for manipulating these numbers. Activities with enlarged ten frames enable children to automatically think of numbers less than ten in terms of their relationship to ten, and to build a sound knowledge of the basic addition and subtraction facts for ten, which are an integral part of mental calculation.
Math Vocabulary Words we will be using and discussing. Please have a conversation with your child about them:
Accuracy: Is my answer true? How do I know for sure? Does it matter?
Strategy: What did you already know that helped you find your answer? Did you have more than one way that worked?
Efficiency: I found my answer, but is there a faster, more accurate way? Is this important?
Grouping: Having the same number of objects inside of each group that I am counting. Why is this important? What does it let me do?
Organizing: How can I arrange my objects so that they can be counted efficiently and kept track of?
