Maths in Primary 1 Sorting Classifying sets of objects by a variety of criteria is an ongoing feature of mathematical work throughout the primary years. • by colour • by shape/kind • by size • by own criteria Matching An ability to match members of a set one to one with members of another set is a necessary preliminary to counting. Which has more? Same as & less than Pattern An appreciation of order and pattern is an important part of mathematics. • patterns involving colour • size • shape • combinations of the above • devising their own patterns Number Through practical activities and discussion children will… • learn to recognise and write numerals • learn the order of a number • learn the value of a number • learn to recognise number names two 1 2 3 4 5 6 7 8 9 10 Concept of Number • number rhymes, stories and games • practical activities with a variety of objects: beads, cubes, themselves etc • washing line, drawing, tracing, labelling, painting, cutting & sticking, drawing over dotted lines • using a real context-fruit, shop, giving out materials etc • number lines, smart board Draw 2 Make 3 and 1 Colour 3 red and 3 blue Make 3 Conservation of Number Ordering Number • re -order • number after/before, count forward/backward • add one more/less • remove one – what’s missing/number between • which is bigger/smaller • order numerals, number names, sets of objects 0 1 2 3 4 5 6 7 8 9 10 10 09 08 07 06 05 04 03 02 01 00 8 Increase number range Use number names 1 3 2 4 9 7 6 5 Count in twos Bus Stop first second third fourth Interpreting Data Which fruit is most popular?
