Let’s practice estimating and measuring things. Students draw a chart with
three columns and five rows. They work in pairs.
In the first column, they write the names of five things
they can measure. In the second column, they write their
estimates. Then they measure each thing and write the
actual length, weight, or volume in the third column. If
time allows, they can figure out which pair were best at
estimating.
