Here’s a fun, super easy way to get students to find the factors of a given number. All you need is inch graph paper and stickers. If you like, you can have students create all the rectangular arrays for a given number using tiles then transfer the arrays onto the graph paper using the stickers. CCSS: 4.OA.4
This is a super easy, super fun activity to tie art in with bilateral (mirror) symmetry. These are some samples of third and fourth grade work. CCSS: 4.G.3
Watchthe video below to see how simple objects like tiles, stickers, rubber stamps, dice, and graph paper help teach students important concepts in number theory: factors, primes, composites, and square numbers…not to mention the great reinforcement of multiplication facts. Grades 2 – 5 CCSS: 2.OA.4; 2.NBT.2; 3.OA.1; 3.OA.3; 3.OA.5; 3.OA.7; 4.OA.1; 4.OA.4
Super easy way to have 2nd or 3rd graders physically make each of the multiplication facts. They roll two dice (two different colors, one color for rows and the other color for columns) and create the array using stickers or rubber stamps. Sometimes having them use graph paper helps keep the rows and columns lined up. Also, since a regular die only goes up to 6, you can use dice that has 10 faces. Another options would be to cover…
Okay, so I’m talking about the two most important questions you can ask your kids to help develop mathematical thinking. Wait! Don’t go. Math often receives short shrift. It’s unfortunate because math, taught correctly, teaches us how to effectively problem solve. It’s also the perfect subject to teach our kids persistence. Research has shown that kids who are persistent tend to do better academically. And doing well academically has great benefits in life. The two most important questions: #1: WHY?…
