Math Updates

We are expanding on our math by pushing our thinking with these second grade concepts. Arrays are a focus, so we are relating this to multiplication, while also including repeated addition. Rows and columns are vocab words added to this discussion, and are tough to decipher between. Students are very eager to do more with the extrar challenge!

Tell me about 3x4. What does it mean? How would you solve that problem? (Background knowledge: Multiplication sentences are introduced as the number of groups multiplied by the size of each group; so in that example, 3x4 is 3 groups of 4, 3x4=12, and 4x3 would be 4 groups of 3, 4x3=12. We also talk about the commutative property: 3x4=4x3, etc.)
Tell me about the visual models for multiplication you've learned (equal groups drawing, array, bar model, number line). Which model helps you the most?
