In previous grades, students developed a foundation for understanding place value, including grouping in tens and ones. They built understanding of whole numbers to 120 and developed strategies to add, subtract, and compare numbers. They solved addition and subtraction word problems within 20 and developed fluency with these operations within 10. Students also worked with non-standard measurement and reasoned about attributes of geometric shapes (adapted from Charles A.)

boards, number lines, rulers, virtual manipulatives, diagrams, and concrete geometric shapes (e.g., pattern blocks, three-dimensional solids). Students understand which tools are the most appropriate to use. For example, while measuring the length of the hallway, students are able to explain why a yardstick is more appropriate to use than a ruler.
