Unit 1
Students read, write, compare, and round whole numbers through 1,000,000. The unit builds number sense with models, expanded form, and reasoning about digit value.
First steps
Unit 2
Students build fluent, accurate addition and subtraction with multi-digit whole numbers. They connect place-value strategies, estimation, and written algorithms to solve problems and explain their thinking.
First steps
Unit 3
Students develop multiplication fluency and conceptual understanding using arrays, area models, and place-value strategies. The unit strengthens fact recall and multi-digit multiplication reasoning.
First steps
Unit 4
Students interpret division, use facts and place-value strategies, and solve division problems with remainders. They connect multiplication and division and explain the meaning of remainders in context.
First steps
Unit 5
Students investigate factors, multiples, prime and composite numbers, and numeric patterns. The unit develops algebraic reasoning and supports multiplication and division fluency.
First steps
Unit 6
Students build conceptual understanding of fractions as numbers, compare fractions, and generate equivalent fractions. Visual models and number lines support flexible reasoning.
First steps
Unit 7
Students connect mixed numbers and improper fractions and reason about fractions greater than one. The unit uses visual models, number lines, and decomposition of wholes.
First steps
Unit 8
Students add and subtract fractions and mixed numbers with like denominators. The work emphasizes visual meaning, decomposition, and application in context.
First steps
Unit 9
Students represent tenths and hundredths as decimals, relate decimals to fractions, and compare decimal values. The unit emphasizes place value and connections among number forms.
First steps
Unit 10
Students solve problems involving customary and metric units, elapsed time, and measurement in real contexts. The unit emphasizes equivalence, estimation, and efficient strategies.
First steps
Unit 11
Students measure and solve problems involving perimeter and area and build geometric vocabulary for lines and polygons. The unit connects formulas to visual models and classification.
First steps
Unit 12
Students identify, measure, and reason about angles, including right, acute, and obtuse angles. They explore points, rays, straight angles, and angle relationships along a line.
First steps
Unit 13
Students represent and interpret data using bar graphs, picture graphs, line plots, and tables. They reason about fractional measurement data and introductory ideas of center.
First steps
Unit 14
Students use variables and symbols to represent problems, solve one- and two-step equations in context, and graph ordered pairs in the first quadrant. The unit blends arithmetic structure with algebraic thinking.
First steps
Unit 15
Students solve richer multi-step problems that combine operations, fractions, measurement, and estimation. The focus is on selecting efficient strategies and justifying why they work.
First steps
Unit 16
Students deepen understanding of numerical structure through properties, equivalence, and pattern-based reasoning. Problems emphasize flexible thinking while staying within grade-level content.
First steps
Unit 17
Students integrate ideas across the year through cumulative tasks that blend number sense, operations, fractions, geometry, measurement, data, and algebraic reasoning. The unit is designed to consolidate mastery and prepare students for advanced in-grade applications.
