Activities for the 100th Day of School

It’s hard to believe that 2018 is here, and we’re quickly approaching the 100th day of school. When I first started working with elementary school teachers, the concept of a 100 days celebration was foreign to me—it wasn’t something that we did in high school. Over time, I’ve come to appreciate this tradition and the mathematical opportunities it brings. In honor of 100 days of learning this school year, here are a few ideas for your 100th day activities. Try them out and let us know what you think!

Base Ten Blocks: Your Most Important Tool

We often see children who struggle to perform even the most basic operations, even after repeated instruction. Without an understanding of base ten and place value, children are very limited in their ability to do ordinary arithmetic; that is, to add, subtract, multiply and divide. If, for example, they can only think of 48 crayons as 48 individual loose crayons, and 25 more crayons as 25 individual loose crayons, then the only strategies available for finding the total number of crayons are “counting all” (1, 2, . . ., 48, 49, 50, . . . 73) and “counting on” (48 - 49, 50, . . . , 73).

Why Must Measurement be a Focus for Grade K-3 Students?

Primary children are expected to learn to count, add/subtract, and solve simple word problems in mathematics. So why must a focus at this level also include measurement concepts and skills? Obviously, measurement is of great importance in our daily lives. Those who have worked with K-3 students know that measurement topics are not easy for many children to understand. Measurement must be a focus at the primary level because students need a wide variety of conceptual experiences to make sense of what they are learning; this emphasis prepares them for later work in mathematics.

Fractions are Only the Beginning

When first introduced to fractions, students in the intermediate grades sometimes struggle to make sense of equivalence and fraction operations. By helping students develop a deep understanding of the role of factors in comparison and fraction operations, we also prepare them for topics that follow and that build upon this knowledge.

Many of the tools used to introduce these early fraction concepts can also be used later to help students recognize the relationships between fractions and ratios, rates, and proportions. Fractions with Prime Factor Tiles is the perfect tool to introduce and explore these concepts.

Making Sense of Numbers on the 120 Board

When I first started visiting elementary school classrooms, I noticed that almost all of them had a hundreds chart somewhere in the room. It might have been a pocket chart, or maybe a poster on the wall, but it was always there as an instructional tool. Then, about ten years ago, the mathematics community agreed that rather than stopping at 100, this chart should go to 120. This change would address students’ struggles with “turning the century,” helping them recognize that the number after 100 is 101 and that counting continues from there.

Conceptualizing Equivalent Fractions

Helping students build an understanding of fraction concepts is a challenge in the intermediate and middle grades. The pictorial representation is a critical tool for making the connection between the concept and the procedure. Conceptual understanding occurs when students can explain why the procedure works, showing that they have assimilated or integrated this understanding into their basic knowledge of fractions.

Domino Fun with Math Concepts

Traditional dominoes have a variety of uses in the classroom. A simple internet search for “math domino games” yields thousands of ideas for using these tools to build number concepts. But eventually, the novelty wears off and they become more of a toy than a learning tool. But the matching aspect of dominoes lets us expand this teaching tool to domains beyond number.

Math is Fun with Kinesthetic Activities

While on hall duty during my first year of teaching, I was surprised to see our math department chair leading her Calculus students to a large common area in the school. Curious, I checked in on them a few minutes after the class had started and found that they were plotting “points” by standing on a large coordinate grid mat on the floor. After watching the teacher use those mats over and over with students in Algebra 1 all the way through Calculus, I realized the value of this kinesthetic learning experience. Her students understood the concepts better, and were more engaged, because they were out of their seats and actively creating a life-sized visual model.
