Read, represent, compare and order decimal tenths, in various contexts.

The Ontario Mathematics, Grades 1–8 outcome B1.7 (Number) for Grade 4 says: “Read, represent, compare and order decimal tenths, in various contexts.” This Fieldbook unit teaches it hands-on, with everyday materials and a printable teacher guide and student sheet for every lesson. Official wording: Ontario Mathematics, Grades 1–8.

Fair Shares: Fractions and Decimals Grades 3–4

Is half always the same size? Where does three-quarters stand? Why is 3/4 + 2/4 not 5/8? Who jumped further, 1.4 m or 1.35 m? Four hands-on lessons where students fold, stand on a giant number line, measure recipes and measure their own jumps to make sense of fractions and decimals.

  • Who jumped further, 1.4 m or 1.35 m? 50–60 min

    Students do standing long jumps, measure them to the centimetre and write them as decimals of a metre, then settle an argument: is 1.35 m further than 1.4 m because 35 is bigger than 4? Students explain tenths and hundredths with a metre stick, write them as fractions and decimals, and compare decimals correctly.
