Why Learning Trajectories?

Want to help children to be confident in their math abilities?

Learn about the steps children typically take to learn math by exploring LTs. Each topic (or trajectory) is broken down into the levels, or steps, children take on their path to being strong mathematicians.

Explore LTs to find your child's level.

Click on the green Activities button in that level for math games, math activities, and math lessons.
