This Doubles and Halves 3 presentation also includes:
Build mental math skills by teaching learners to double and half three-digit numbers. They start out by doubling one of seven double-digit numbers. Next, they discuss their strategy, and then practice doubling and halving 3-digit numbers. They also practice doubling in each place value, then adding those new values together. This is a great way to build number sense while providing a problem-solving strategy.
