Reception

Year 1Tell the time to the hour and half past the hour and draw the hands on the clock face to show theseTips: use analogue clocks- not digitalYear 2Tell the time to 5 minutes including quarter past/toTips: use analogue clocks-to set times- ie tea at half past five use language of 1/2 past 1/4past

Year 3 Read the time on a 12–hour digital clock and to the nearest 5 minutesRead an analogue clockCalculate time intervals and find start or end times for a given time intervalIntroduce ROMAN NUMERALS

Year 4Read time to the nearest minuteUse am, pm and 12-hour clock notationChoose units of time to measure time intervals, e.g. seconds, minutes or hoursCalculate time intervals from clocks and timetables

Year 5Read timetables and time using 24-hour clock notationUse a calendar to calculate time intervals

Year 6All the above plus read from digital and analogueSolve multi-step worded problems including reading and interpreting timetables

How long is the movie?

•I started watching a movie at

3:30 pm and it ended at 4:45 pm.

In Year 2 and Year 6 the children take National tests

called SATs in Maths.

Here are some examples of types of questions, more can be found online.

Level 4 questions

What can I do to help?

Mental maths games

• Times table practice• Set times for your child on an
