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…
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…
Here’s a super simple activity that helps students to “see” multiplication facts. It’s also a great way for them to see the connection between addition and subtraction as they “use addition to find the total number of objects arranged in rectangular arrays” (CCSSM 2.OA.C.4) and to “interpret products of whole numbers” (CCSSM 3.OA.A.1). Using inch graph paper, have students make rectangular arrays and record the rows (horizontal) and columns (vertical) as multiplication equations. This is a good time to discuss…
I just finished reading the book How Children Succeed: Grit, Curiosity, and the Hidden Power of Character by Paul Tough. Here’s how I summarized it on my Family Math Night facebook page: “Kids succeed in a stress-free, nurturing environment where delayed gratification is encouraged and perseverance is developed through “managed” failure.” Instead of writing a long book review, I thought I’d simply list below all the sentences I highlighted while reading the book. It will give you a good idea…
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…
