Learning focus

Learn to calculate start times, finish times and durations.

This lesson includes:

• reading tables and timetables
• two activities

Mae 24 awr mewn diwrnod.

Gallen ni fesur y diwrnod wrth ei wahanu i mewn i ddau hanner.

• Yr enw ar y 12 awr cyntaf - o hanner nos tan hanner dydd - yw'r bore.
• Yr enw ar y 12 awr nesa - o hanner dydd tan hanner nos - yw'r prynhawn.

*There are 24 hours in a day. *

We can measure the day by dividing it into two halves.

• We call the first 12 hours - from midnight to midday - the morning.
• We call the next 12 hours - from midday to midnight - the afternoon.

Edrycha ar y clociau isod. Wyt ti'n gallu dweud faint o'r gloch ydy hi ar bob un?Dyma gyfle i ti ymarfer cyn gwneud y gweithgareddau.

Look at the clocks below. Can you tell what time it is on each clock?This is a chance for you to practise before doing the activities.

Gweithgaredd 1 / Activity 1

Amserlenni bws

Dyma amserlen bws sy'n dangos faint o'r gloch mae'r bysys yn gadael a chyrraedd.
