Visual prompts explain how to find the intervals between unmarked lines on a number line and link the skill to measuring, such as telling time and using rulers, beakers, and thermometers.
The number lines start with easier problems and gradually become more complex. Earlier pages help students practice finding the intervals between the unmarked lines. Number lines in later pages are designed for specific measuring objectives, such as intervals commonly seen on a thermometer or beaker (5’s, 10’s, 25’s, 100’s etc.). One page covers measuring in centimeters. The final pages include a special set of instructions for connecting number lines and fractions. This is particularly useful for teaching standard ruler measurements. The Fraction Pyramid Cards are a great visual aid to demonstrate how an inch is broken down into fractions, and how to know whether a line is a 1/2, 1/4, 1/8, or 1/16.

2. Understand a fraction as a number on the number line; represent
fractions on a number line diagram.
3. Explain equivalence of fractions in special cases, and compare
fractions by reasoning about their size.
