Mathematical properties are actually quite useful when it comes to making sense of math. For example, the commutative property of addition helps make adding numbers a little easier. If we know that the order the numbers are added does not matter, then in the problem 2 + 9, adding the 2 onto the 9 is easier and more efficient than adding the 9 onto the 2. The Common Core State Standards in Mathematics requires all third grade students to know…
Making sense of and understanding mathematics is the foundation of the new Common Core State Standards in Mathematics. It is not enough that kids can compute with numbers – they must understand why those computations work. Enter Number Theory, the part of math that explores numbers and how they relate to each other. At the heart of Number Theory are the properties of number. One of the first ones students will encounter is the Commutative Property of Addition. It states…
Got lots of left-over greeting cards? Here’s one fun way I found to use them with kindergarten and first graders. I sort the cards into two categories and the students try and figure out my rule. In the example above, I sorted the cards into pumpkins and hearts. It was pretty easy for students to figure that one out. But, after that, they can get pretty tricky and student really need to look carefully for similarities within groups: cats vs…
