Ordering 3-Digit Numbers The teacher will demonstrate ordering 3-digit numbers. Model solving problem #1 (page 64) using the process as before. Main Idea: list least to greatest girls’ scores Details/Known: M - 322 points L - 223 points S - 232 points The teacher and student table groups build each number from the story problem with base 10 blocks on mats. Have students draw a picture to represent each number beside the corresponding “detail.” Details: M 322 points L 223 points S 232 points As before, students discuss how to arrange the mats from least to greatest. Then they place the mats in order. Ask the students, did you decide which number would go first, second, and (Have several “How third?” students explain their thinking.)
