Biology Tessellations
Students review three types of polygons that are triangles, squares, and hexagons. They use a computer program to draw various types of tessellations. The students use the drawing of a honeybee as inspiration.
Curated OER
Fractions
First graders are asked to put their fingers on their triangles that looks like the one that is on the overhead. They are asked to tell how they would write a fraction for this one part. Students go through step one until all of the...
Curated OER
What's Your Function?
Second graders read the rules of how they can balance the scale by placing beans in the square, circle, and the triangle. Next, they balance 12 beans using the scale and then try to balance it with 15 beans, and then 18 beans. They then...
Curated OER
Five Fat Turkeys
Students make a tree trunk and branches using brown construction paper. They make thumbprint turkeys using a choice of ink color. Students make the eyes from wiggle eyes and of black ink. They make the beak out of any color foamie triangle.
