Multiply 2-5 Groups Fluently with Equations 3-33
Transition from using number bonds to writing equations and using mental math. What's 3x5? Visualize 3 groups of 5 as 2 groups of 5 and 1 group of 5. Since 2x5 = 10 and 1x5 = 5, 3x5 = 10+5 = 15. Find and add partial products to get the total product – the distributive property. The goal is fluency first, then automaticity.
