Place any fraction on a number line with endpoints 0 and 1. Analyze different rectangles and reason about their area. Tessellate to understand perimeter as the boundary of a shape. Decompose twice to subtract measurements including three-digit minuends with zeros in the tens and ones places. Please submit your feedback or enquiries via our Feedback page. Compare fractions and whole numbers on the number line by reasoning about their distance from 0. Reason about and explain arithmetic patterns using units of 0 and 1 as they relate to multiplication and division. Round to the nearest hundred on the vertical number line.

Round two- and three-digit numbers to the nearest ten on the vertical number line. Solve word problems involving time intervals within 1 hour by adding and subtracting on the number line.
