Three “Tools” that Promote Mathematical Thinking

Three “Tools” that Promote Mathematical Thinking

One of the best ways to engage young children in math is to make it hands-on. Here are three hands-on tools that can give kindergartners opportunities to do some great mathematical thinking in the context of…them. Bathroom Scale: The bathroom scale is a fun math “tool” to have in the house because it gives kids immediate feedback and, the best part is, it’s all about them! Unlike a lot of adults who may not like standing on a bathroom scale,…

Name Patterns: A Fun First Week of School Activity

Name Patterns: A Fun First Week of School Activity

Patterns. It was always a theme throughout the school year in my mathematics classes. So to kick-off patterns, during the first week of school, the students create a color pattern using their name. Then, we discuss the patterns made by names of different lengths. It may seem like a simple activity, but some great conversations can be generated when students focus on the reasons why certain patterns appear. For example, in the photo above, there are 15 squares in each…

Subitizing with Dominoes

Subitizing with Dominoes

I love doing this activity with kindergartners and first graders! Not only is it a great way for them to practice their addition facts but these little guys LOVE writing on their individual white board, so it’s a win/win! And it’s so simple. Here’s what you do: Without turning it on, put ONE domino on the overhead projector or doc camera. Tell students that you are going to flash a domino for a few seconds and their job is to…

Reason Abstractly and Quantitatively

Reason Abstractly and Quantitatively

Estimates help us predict the reasonableness of an answer. Having students make an estimate before they perform the calculation, and even writing the estimate next to the problem, can help them to focus on making the numbers (and the problem) make sense. Example: 3.2 x 9.8 = Students use benchmarks to determine that 3.2 is close to 3 and 9.8 is close to 10, therefore, a reasonable estimate would be 3 x 10 = 30. If students perform the actual…

Cookie Fun Way to Teach Money, Arithmetic, and Geometry

Cookie Fun Way to Teach Money, Arithmetic, and Geometry

Cookies in math class? Absolutely! This fun and engaging hands-on activity will get your students excited about doing math. Students will be designing their perfect cookie within the limits of a budget. They will be filling out order forms for cookies, candy and frosting then designing and drawing their final product. This fun activity seamlessly ties in important concepts in math, specifically, addition, subtraction, multiplication and division with money, and attributes of geometric shapes. This lesson is divided into grades…
