Help your Year 1 pupils build fluency and confidence in counting, reading and writing numbers to 100 in numerals with this carefully structured lesson. Designed to meet the Year 1 National Curriculum objectives for place value, this ready-to-use PowerPoint guides children through recognising, sequencing and writing two-digit numbers up to 100. The lesson begins with a lively recap activity, using a hundred square and counters to practise counting forwards and backwards between 20 and 50. Pupils then extend their learning to numbers up to 100, exploring how two-digit numbers are made up of tens and ones. Using clear animations, the slides highlight pronunciation and spelling misconceptions (such as confusing thirteen and thirty ) while modelling how to say numbers correctly. Children are encouraged to spot patterns, identify numbers on a hundred square, and write them in numerals, reinforcing their place value understanding. The independent practice allows pupils to: Read circled numbers on a hundred square and record them in numerals. Write dictated numbers on whiteboards and check against visual models. Work collaboratively to order number cards 20–100 into a class number line. The plenary addresses common misconceptions such as digit reversal and the role of zero in two-digit numbers (e.g., 40 = four tens, zero ones). This engaging resource is ideal for whole-class teaching, small group support, or home learning, helping children to confidently count, read and write numbers up to 100 in numerals.
This pack is listed as editable, so the editable copy comes with it. We do not print page counts here, because our catalogue does not publish them and a guessed number is worse than none.
