Challenge: Try out Étienne’s Math Raps, then make one of your own!

Acceleration:

To speed from zero to more at any rate

That increase of speed means accelerate

Acceleration is how fast velocity ranges

Watch for the time and distance changes

Acute Triangles

Some triangles aren’t right, some are just ugly

Others are acute, with little angles so snuggly

Like in all triangles, acute angles come in threes

But every single one of them is less than 90 degrees

Angles:

Angles should not perplex

Two points meet at the vertex

The amount of turn between two lines

Try some, make some, you’ll be fine

Let’s add a little motion. Stand up and try the 180-90-45 Straight-Right-Acute Angles dance!
