Unit 1
Students build strong number sense to 1,000 using place value, number names, and multiple representations. The unit blends daily practice with visual models and clear structure.
First steps
Unit 2
Students compare numbers, use benchmarks, and develop flexible mental strategies. The unit supports reasonableness and efficient thinking before formal computation.
First steps
Unit 3
Students build addition fluency within 100 through fact strategies, regrouping, and problem solving. Lessons move from concrete models to efficient written methods.
First steps
Unit 4
Students subtract within 100 using place value, related facts, and regrouping. The sequence emphasizes meaning and efficient methods with consistent review.
First steps
Unit 5
Students extend place-value methods to 3-digit numbers. They add and subtract with conceptual models, written methods, and reasonableness checks.
First steps
Unit 6
Students solve one-step and two-step addition and subtraction problems using bar models, equations, and clear reasoning. This unit strengthens communication and mathematical reasoning.
First steps
Unit 7
Students build the meaning of multiplication through equal groups, arrays, skip-counting, and repeated addition. The focus is conceptual and in-grade, not rote fact acceleration.
First steps
Unit 8
Students build the meaning of division through fair sharing and making groups. The unit connects division to subtraction, multiplication, and real stories.
First steps
Unit 9
Students understand fractions as equal parts of a whole and as parts of sets. The emphasis is on visual reasoning, fair shares, and precise language.
First steps
Unit 10
Students measure and compare using common units and appropriate tools. They also solve practical measurement problems using estimation and data.
First steps
Unit 11
Students tell time to five minutes, use A.M. and P.M., and solve simple elapsed time situations. They also count mixed coins to one dollar, find equivalent amounts, decide if they have enough money, and make change in simple contexts.
First steps
Unit 12
Students describe, sort, build, and combine 2D and 3D shapes. They also notice lines, curves, and angle counts in simple figures.
First steps
Unit 13
Students represent and interpret data, explore beginner probability, extend patterns, and solve equations with unknowns. The unit highlights connections among representations, operations, and reasoning.
First steps
Unit 14
Students choose among addition, subtraction, multiplication meaning, and division meaning to solve mixed story problems. The unit includes required two-step structures and reasoning with one- and two-digit numbers.
First steps
Unit 15
Students deepen Grade 2 understanding through richer problem structures, larger within-grade numbers, and flexible strategy choices. The focus remains within Grade 2 standards while increasing complexity and independence.
First steps
Unit 16
Students synthesize Grade 2 ideas across number, operations, measurement, geometry, data, time, money, and fractions. Tasks emphasize explanation, model choice, and strategic thinking with in-grade rigor.
