Read and write numbers from 0 to 1,000 using standard form, expanded form and word form.

Compose and decompose three-digit numbers in multiple ways using hundreds, tens and ones. Demonstrate each composition or decomposition with objects, drawings and expressions or equations.

Plot, order and compare whole numbers up to 1,000.

Round whole numbers from 0 to 100 to the nearest 10.

Recall addition facts with sums to 20 and related subtraction facts with automaticity.

Identify the number that is ten more, ten less, one hundred more and one hundred less than a given three-digit number.

Add two whole numbers with sums up to 100 with procedural reliability. Subtract a whole number from a whole number, each no larger than 100, with procedural reliability.

Explore the addition of two whole numbers with sums up to 1,000. Explore the subtraction of a whole number from a whole number, each no larger than 1,000.

Partition circles and rectangles into two, three or four equal-sized parts. Name the parts using appropriate language, and describe the whole as two halves, three thirds or four fourths.

Partition rectangles into two, three or four equal-sized parts in two different ways showing that equal-sized parts of the same whole may have different shapes.

Solve one- and two-step addition and subtraction real-world problems.

Determine and explain whether equations involving addition and subtraction are true or false.

Determine the unknown whole number in an addition or subtraction equation, relating three or four whole numbers, with the unknown in any position.

Represent an even number using two equal groups or two equal addends. Represent an odd number using two equal groups with one left over or two equal addends plus 1.

Use repeated addition to find the total number of objects in a collection of equal groups. Represent the total number of objects using rectangular arrays and equations.

Estimate and measure the length of an object to the nearest inch, foot, yard, centimeter or meter by selecting and using an appropriate tool.
