One of the best ways to teach students geometry vocabulary is to simply look around our environment. For example, if you want students to understand parallel lines, pair them up and hand them an individual white board and take a stroll around the school. Have them write down all the parallel lines they see. Here are two examples of parallel lines in our environment. Check out all the parallel lines in the door, the windows, the bookshelf, even the light…
Here’s a GREAT way to teach long division in a way that uses estimation skills and number sense. In addition, it helps solidify the relationship between multiplication and division. If we can provide our students with a variety of strategies to solve math problems, then math becomes accessible to more students. CCSS: 4.NBT.6; 5.NBT.6
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
