Estimating is important. If we estimate accurately, it helps us check if our actual measurements are accurate.
We can record our measurements in a table, which is a presentation of information so data can be interpreted easily.

Children may estimate incorrectly or confuse where to record their measurements in the table.

When estimating, hold an item of known mass in one hand and the unknown in the other - compare them. Take care when reading table headings.

Estimate - An estimate is a given value, number or quantity that is near to the true amount; it is a number close enough to the right answer.
Table - A table is data (a collection of numbers, words, measurements and descriptions of things) arranged in rows and columns.
