Measurement & Data Lessons for Grade 1
Compare lengths, order objects from shortest to longest, and tell time to the hour and half-hour. The diagrams move with you, so measuring feels like comparing real things. Every lesson opens with a moving diagram you can touch and explore, followed by simple words that explain the idea.
