Primary students (K-2): counting, colors, shapes, sorting and classifying
Intermediate students (3-5): counting, sorting and classifying, logical thinking
It was the week before Valentine's Day and I was committed to using conversation hearts in my 'What Do You Notice?' poster. I thought a venn diagram would work nicely. A venn diagram illustrates the common attributes between sets. In our case, the first circle is the set of numbers greater than 5 and the second circle is the set of numbers less than 10. The intersection of the circles are the numbers that fit both sets - 6, 7, 8, and 9.
This was a pretty tough venn diagram to figure out so I decided to give a hint. The total number of letters on each heart determines where each conversation heart is placed. In order to get enough hearts for my circles, I had to make up some of my own phrases. For fun, I included a Challenge! question.
Younger students can count the different number of colored hearts or even the total number of hearts. And, of course, they may notice the two large circles.
"Every heart has 4 but blue has 3."
"left circle > 5; right circle < 10. It would go in the center."
"4 pink hearts"
"There's more green and yellow than others."
