Math Slide: Tens & Ones

My favorite aspect of the Math Slide series is the variety of representations they use for numbers. The early levels start with very simple fundamentals that still make kids think, and then levels build to an impressive level of complexity. As a first grade teacher, I primarily use the Math Slide Tens and Ones (also called Math Slide 100.) The addition and subtraction is another good one. All four apps in the series are excellent!
