Use computational fluency to add and subtract three-digit whole numbers, using strategies and algorithms based on place value, properties of operations, and/or the relationship between addition and subtraction

Apply properties of operations as strategies to multiply and divide

Use strategies to multiply one-digit numbers by multiples of 10 ranging from 10-90; strategies are based on place value and properties of operations (e.g., 9 ∙ 80, 5 ∙ 60)

Identify arithmetic patterns including, but not limited to, patterns in an addition or multiplication table, explaining use of properties of operations appropriate to the pattern

Solve real-world problems using multiplication and division within 100 involving equal groups, arrays, partitive and measurement division

Solve two-step real-world situations using addition, subtraction, multiplication, and division, representing these problems using equations with a symbol standing for an unknown quantity

Determine the unknown whole number in a multiplication or division equation relating three whole numbers

Understand division as an unknown-factor problem

Represent a data set with multiple categories, using a scaled picture graph, scaled bar graph, and a line plot

Solve one and two-step problems, using categorical data represented with a scaled picture graph, scaled bar graph, and a line plot

Recognize rhombuses, rectangles, and squares as examples of quadrilaterals, identifying and/or drawing examples of quadrilaterals that do not belong to any of these subcategories

Describe area as the number of unit squares that cover a plane figure without gaps and overlaps

Find the area of a rectangle with whole number side lengths by modeling with unit squares and multiplying the side lengths to show the results are the same

Multiply side lengths to find areas of rectangles with whole number side lengths in the context of solving real-world and mathematical problems

Solve one-step real-world problems involving liquid volumes and masses of objects in the same units, using all four operations

Solve word problems involving addition and subtraction of time intervals in minutes

Round four-digit whole numbers to the nearest 10 or 100, using place value understanding

Compare two fractions with the same numerator or denominator by reasoning about their size based on the same whole; use symbols (<, =, >) and justify the conclusion using visual fraction models, concrete objects, or words

Partition squares, regular hexagons, and equilateral triangles into parts with equal shares, explaining the shares of each part as a unit fraction of the whole

Identify and represent a unit fraction as a number on the number line

Identify and represent a non-unit fraction as a number on the number line, including fractions greater than one

Decompose and compose a non-unit fractiona/bas the quantity formed by the sum of unit fractions

Use number lines and visual models to recognize and generate equivalent fractions, explaining how they are equivalent in real-world and mathematical situations
