What Do You Notice? Dominoes

Skills

Primary students (K-2): colors, patterns, counting, sorting and classifying, addition

Intermediate students (3-5): patterns, sorting and classifying, addition

Mathematical Background

I created this Venn Diagram with dominoes thinking it was going to be too easy. It turned out to be harder than I thought. The left circle is all even numbers and the right circle is sums between 2 and 8. Finding the common attributes of both circles was quite the challenge. That said, students still made some nice observations.

Sample Student Responses

"2 of each color."

"“3 in the middle, 4 on the right, 5 on the left.”"

"“left and Both are even. Right is odd.”"

"“There are 12 all together.”"
