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
Students use sticky dots to create a caterpillar with a head and 10 body parts. They add eyes, a mouth, and antennae to the head. Then they add two legs to each body part. Finally, they skip count by 2s and write in the number. For the younger ones, I provide a 0-110 number chart for them to use as they write in the numbers. . . . Oops…I didn’t catch this one in time. Her caterpillar is skip counting…
Meaningful math with a purpose! This great hands-on lesson gets students doing math while designing targets. Students become comfortable using the area formula for circles. And the best part is, their targets are set up and used during the school’s fall carnival. Watch the video below for the entire lesson plan. CCSS: 7.G.4 TEKS: 6th grade 6C, 8A, 8B Link to video. .
There’s no better excuse to have kids counting all day than the 100th day of school. Often, teachers have students bring in 100 of something that they sort into groups of 10 (you can also have each student bring in 10 of something and then combine them to make 100). Or maybe it’s a project made with 100 of something. Or making tally marks and skip counting by fives to 100. Whatever you choose, it’s the perfect way to celebrate…
This is one of my favorite math and art activities. That’s because it involves a mathematical pattern. Using centimeter graph paper, we start with the basic unit which, in this case, is simply one square. I then ask students what they think the area would be if we doubled the size of the square. The first thing they blurt out before thinking is “two”. I then use the graph paper to show them that if I double the square (double…
