Students will use number lines to round numbers under 100 to the nearest 10 throughout this worksheet.

Section A begins with looking at the number bonds to 10.

In section B, students will complete number sequences of multiples of 10, including 3-digit numbers.

Section C begins with an example which demonstrates how to use a number line when rounding. Pupils are encouraged to mark the number to be rounded on the number line before deciding which multiple of 10 it is closest to. Each question comes with its own number line.
