1. Represent and compare three-digit numbers using place-value models, number lines, hundred charts, and expanded form.
Objectifs d'apprentissage:
1. Build and record three-digit numbers with base-ten blocks and write the number in standard and expanded form.
2. Compare and order up to four three-digit numbers using >, <, = and a number line or hundred chart.
3. Decompose a three-digit number into hundreds, tens, and ones in more than one way (e.g., 12 tens + 6 ones).
4. Identify the value of each digit in a three-digit number and explain how place affects value using a place-value chart.
2. Compute sums and differences within 100 using place-value strategies, number lines, hundred charts, and written equations, demonstrating fluency within 20.
Objectifs d'apprentissage:
1. Recall from memory sums and differences within 20 using strategies such as make ten, doubles, and fact families.
2. Add and subtract two-digit numbers with and without regrouping using base-ten drawings or blocks; record the matching equations.
3. Represent addition and subtraction on a number line or hundred chart to justify strategies.
4. Solve one- and two-step word problems within 100 with unknowns in all positions; write and check an equation using the inverse operation.
