Scaffolded Math and Science on Instagram: "Simplifying expressions by combining like terms. When students ask if cubes and squares combine, I like to draw a square on the board, continuously trace over it and ask them to tell me when I’ve made a cube. They pretty immediately tell me that’s not possible and I like to think this helps solidify that squares and cubes are different dimensions and can’t combine. #mathvideo #exponents #mathteacher #liketerms #visualmath"
