Math

K - 4

Interactive math and reading activities

Free units that help students apply math to the world around them. Include units on probability, patterns and functions, fractions, decimals, percentages, data collection and analysis, and more! Though they say for grades 4-8, I would recommend for 3rd to 4th grade gifted typically.

Collection of online math games

This is a completely free resource that allows students to learn about stocks, bonds, mutual funds, diversification, and more while playing a simulation that mimics the Stock Market exactly! They get to compete with students across your district, region, and the entire US to see who can invest $100,000 the best. There are fall and spring sessions for competition, so sign up ahead of time, teach students a few lessons in advance so they know the basics, then start competing!
