Number Line: Solving problems [TEKS Tools Grade 4]

This post specifically looks at how number lines can be used to use number lines to solve problems. Read more about TEKS Tools and their rationale here.

Number Pairs

Number lines, the second TEKS Tool, account for around 20% of each 4th grade STAAR test. Within this tool are many uses: representing and comparing fractions, interpreting number pair relationships, and solving problems involving rounding and the operations.

The main function of a number line is to show the relationship between fractional quantities, number pairs, or as a tool for rounding and estimation. By visualizing these quantities on number lines, students can better make sense of the how the quantities are related.

Rounding/Estimation

Students first learn to round numbers by reasoning about a number's relative proximity to a benchmark number. Utilizing number lines increases conceptual understanding that builds to the rounding algorithm.
