## Using Strip Diagrams as a Problem-Solving Strategy

There’s a lot to be learned from the data that comes from state testing if we use it correctly. Oftentimes, we’ll take a problem that students, as a whole, perform poorly on and we create a bunch of problems just like that one and “teach” them...

## Composing and Decomposing Fractions

Not too long ago I wrote about the power of part/whole thinking, and how an understanding that begins in Kindergarten has tons of applications throughout the elementary curriculum. Here’s yet another one. Take a look at this fraction addition problem. Think...

## Visualizing Fractions {EQUIVALENT FRACTIONS FREEBIE}

How important is it that our students understand fractions? According to a study conducted by Carnegie Mellon University, it’s super important. The research team found that fifth graders’ understanding of fractions and division predicted high school...

## Composing 100

Ten is obviously an important benchmark in our number system. In Kindergarten, learning the combinations of the numbers up to ten is a year-long process. Ten-frames are an ideal tool for exploring combinations for ten. Because of its relationship to ten, one hundred...

## Coin-Counting Routine

I always love it when I can help kids see mathematical connections between seemingly unrelated skills or concepts. For example, think about the skills required for both telling time and counting money. When you do either, you skip count by one number and then switch...

## Comparing Numbers with Counters

Early experiences with numbers in Kindergarten simply must include the use of manipulatives. Concrete learning helps students visualize the math concepts they are learning and lead to greater number sense. Let’s see how using counters to compare numbers benefits...
