Estimation 180
Estimation 180 is an incredible resource that builds number sense and helps kids flexibly think about numbers with purpose and accuracy. Estimation 180 encourages making sense of problems and persevere in solving them, mathematical reasoning, classroom discourse, and so much more. Hundreds of images are offered for children to analyze and consider as they determine things like, “how tall is Mr. Stadel?” or “How many staples are in that box?” Children use what they know about the situation, ask questions to learn and think about it more, and determine reasonable answers to their estimations. An incredible tool for any elementary classroom!
