Look at this pattern:
2×4=8
3×4=12
4×4=16. What do you notice?
The answers keep getting bigger by 4 each time (8, 12, 16). Every time you multiply by 4, you add another group of 4.
Explain why 4×5 will always give you an even number. Use pictures, words, or equations to prove your thinking.
4 is an even number. When you multiply an even number by any number, the result is always even because even numbers are made of groups of 2. Four groups of 5 can be rearranged as 2 groups of 10, which is even.
