1 Early Maths Play: Sorting, Matching, Comparing and Ordering 14 lessons · about 14 hours

The pre-number bedrock of the year, opened through real objects and talk: sorting and matching by one attribute, one-to-one correspondence, more and fewer, direct comparison and ordering by size. No numerals and no counting demands, so every child succeeds from the first week and the maths-box routines that carry the whole year settle in.

  1. 1 Our Maths Box: Things That Go Together Sample lesson
  2. 2 Sorting by Colour
  3. 3 Big and Small
  4. 4 What Belongs Together: Sorting by Kind

2 The Numbers 1, 2 and 3 13 lessons · about 13 hours

Meeting the first numbers properly. Pupils touch-count little sets, recognise and begin to form each numeral, match numeral to set, build the first counting stairs, meet 'one more', and discover that three stays three however it is arranged. Every context is an infant's own world: songs, teddies, birthdays and the numbers on doors and buses.

  1. 15 The Number 1: Just One
  2. 16 The Number 2: A Pair
  3. 17 Writing 1 and 2: in the Air and in the Sand
  4. 18 The Number 3: the Three Bears

3 Numbers 4, 5 and Zero: Making and Breaking Little Sets 15 lessons · about 15 hours

Extending the counting world to 4, 5 and zero, then moving from counting sets to making and breaking them: partitioning 4 and 5 onto two plates, joining little sets, and finding a hidden part. Everything stays in objects and talk ('3 and 2 make 5'); there are no plus, minus or equals symbols at this stage. Five becomes a landmark: one whole hand, one full row of the ten-frame.

  1. 28 The Number 4: Alice the Camel's Humps
  2. 29 Sets of 4 All Around: the Wheel Hunt
  3. 30 Writing 4
  4. 31 The Number 5: One Whole Hand

  10. 37 Writing 0 and Counting Down: Blast-off!
  11. 38 Breaking 4: Two Little Plates
  12. 39 Breaking 5: Fingers Up, Fingers Down
  13. 40 Putting Sets Together: and Makes
  14. 41 The Hiding Game: How Many Are Hiding?
  15. 42 The Five Party: Module Review
4 Patterns All Around Us 10 lessons · about 10 hours

Meeting repeating patterns properly: noticing, copying, continuing, creating and fixing AB, AAB and ABC patterns in colours, sounds and actions. The rule is the star: say the pattern out loud and it tells you what comes next. Patterns stay in little hands (cube trains, threading beads, body percussion) with the pattern-blocks interactive as the shared IWB surface.

  1. 43 Patterns All Around Us: What Do You Notice?
  2. 44 Copy My Pattern
  3. 45 What Comes Next?
  4. 46 Patterns We Can Hear and Do
  5. 47 Make Your Own Pattern
  6. 48 The Pattern Hunt: Outdoors
  7. 49 Two the Same, Then One: a New Pattern
  8. 50 Three in the Pattern: Red, Yellow, Blue
  9. 51 Pattern Detectives: Fix the Mistake
  10. 52 The Pattern Party: Module Review
5 Shape and Space: Solids, Flat Shapes and Where Things Are 16 lessons · about 16 hours

Where things are, then what shape things are. Position words through body play and the shop-corner queue, then 3-D solids before 2-D shapes (infants handle boxes and balls long before they meet the flat shapes on their faces), and finally shape movements: rolling, sliding, turning and fitting. Almost everything is real objects: the feely bag, the junk box, ramps and construction play; the interactive appears only late, once flat shapes arrive.

  1. 53 Where Is Teddy? on, in, Under, Beside
  2. 54 Over, Under, Through: the Bear Hunt Trail
  3. 55 In Front, Behind, Between: the Shop Queue
  4. 56 The Mystery Box: Meeting Our Solids
  5. 57 Roll or Slide? the Big Ramp Test
  6. 58 Balls and Boxes
  7. 59 Tubes: the Shape That Rolls and Stacks
  8. 60 Master Builders: Building with Solids
  9. 61 Flat Faces: Printing with Our Solids
  10. 62 The Circle: Round and Round
  11. 63 The Square: Four Sides the Same
  12. 64 The Triangle: Three Sides, Three Corners
  13. 65 The Rectangle: Like a Door
  14. 66 Shape Pictures
  15. 67 Slide It, Turn It, Fit It in
  16. 68 The Great Shape Hunt: Module Review
6 Measures: Long and Short, Heavy and Light, Full and Empty 12 lessons · about 12 hours

Direct comparison across the three measures an infant can get their hands on: length (longer and shorter, taller, wide and narrow), weight (heavier and lighter, and the surprise that big is not always heavy) and capacity (full, empty and which holds more). Everything is compared directly: lining up ends, hefting in two hands, pouring one into the other; no units yet. The balance scales does the truth-telling, at the carpet and on the IWB.

  1. 69 Longer and Shorter: Line up the Ends
  2. 70 Taller and Shorter: Towers Side by Side
  3. 71 Wide and Narrow: Roads for Our Cars
  4. 72 Short, Middle-sized, Long: the Washing Line
  5. 73 Heavy and Light: the Two-hand Test
  6. 74 The Balance Scales Tells the Truth
  7. 75 Big Is Not Always Heavy
  8. 76 Full and Empty
  9. 77 Which Holds More? the Pouring Test
  10. 78 Guess How Many: the Button Jars
  11. 79 The Teddy Bears' Sports Day: Measures Outdoors
  12. 80 The Measures Fair: Module Review
7 Time: Our Day and Night 8 lessons · about 8 hours

A first sense of time: day and night, the order of the day's events (first, next, last; before and after), and the feel of a long time against a short time. There are no clocks and no days-of-the-week lists at this stage: time is pictures, routines and talk, sequenced with photo cards on the washing line, acted out and sung. No interactive appears in this module; every lesson runs on picture sequencing, rhyme and play.

  1. 81 Day or Night?
  2. 82 Morning Time: This Is the Way We Start the Day
  3. 83 First, Next, Last: Our School Day
  4. 84 Before and After
  5. 85 A Long Time or a Short Time
  6. 86 Bedtime: Night-time Comes
  7. 87 Our Whole Day: Morning to Night
  8. 88 Our Day and Night Show: Module Review
8 Money: the Shop Corner 6 lessons · about 6 hours

First money awareness, entirely through shop play: money is what we swap for things, coins are special and worth looking at closely, one coin buys one thing, and a price tag tells us how many coins to count out. Everything stays tiny: 1c coins in little purses, price tags of 1c, 2c and 3c, no sums and no change. The shop corner, the till and the talk are the whole lesson. No interactive appears in this module; the money lessons run on role play.

  1. 89 What Is Money for? the Shop Opens
  2. 90 Looking at Coins
  3. 91 One Coin for Each: the 1c Shop
  4. 92 The Price Tag: Count the Coins Out
  5. 93 Shopkeeper Day
  6. 94 The Great Class Market: Module Review
9 Counting to 10: Rhymes, Games and the Number Line 14 lessons · about 14 hours

Late in the year the counting world opens up to 10: oral counts forwards and backwards, touch-counting sets to 10, meeting and recognising the numerals 6 to 10 (recognition only, writing these belongs to Senior Infants), seeing little dot patterns at a glance, and the first landmark feel of ten (a full frame, two full hands). Rhymes and games carry every lesson.

  1. 95 The Big Count to 10
  2. 96 The Number 6: the Egg Box
  3. 97 The Number 7: Rainbows and Ladybirds
  4. 98 The Number 8: the Octopus
  5. 99 The Number 9: One Box Empty
  6. 100 The Number 10: the Full Frame
  7. 101 The Counting Stairs to 10
  8. 102 Match the Numeral to the Set: 6 to 10
  9. 103 Dots at a Glance
  10. 104 Counting Backwards from 10: Blast Off!
  11. 105 Ten in the Bed
  12. 106 Counting the World: Steps, Hops and Treasures
  13. 107 Guess, Then Count
  14. 108 The Counting Fair: Module Review
10 Our Class Finds Out: Sets and Picture Graphs 12 lessons · about 12 hours

The year closes with finding things out: asking a class question, collecting one answer from everyone (one cube, one mark, one picture each), lining the answers up fairly so eyes can compare, and reading what the rows say (more, fewer, most of all). Real-object graphs come before picture graphs, and every graph grows from a question the class actually cares about; the tally-chart and pictogram-builder interactives are the shared IWB surfaces, and one picture always stands for one answer.

  1. 109 Sort It, Line It up, See It
  2. 110 Our Big Question: Vote with a Cube
  3. 111 The Shoe Graph: a Real-thing Graph
  4. 112 From Things to Pictures
  5. 113 A Mark for Each
  6. 114 The Picture Graph on the Big Screen
  7. 115 Reading a Graph: More, Fewer, Most of All
  8. 116 How Do We Come to School?
  9. 117 The Traffic Watch
  10. 118 The Beanbag Game: Keeping the Score Safe
  11. 119 The Minibeast Graph: Answer Its Questions
  12. 120 Our Class Found Out: Module Review

What pupils learn

This course introduces junior infants to foundational mathematics through playful, hands-on activities. Children explore sorting, matching, ordering, early number sense to 10, and the composition of small sets. They investigate patterns, 2D and 3D shapes, spatial language, measures, time, money, and simple data collection through picture graphs. Practical, real-world contexts and games build confidence, curiosity, and mathematical thinking.

By the end of the course, pupils can

  1. Sort a collection of objects into groups by colour, size or kind and explain the rule used.
  2. Recognise, name and write the numerals 0 to 10 and match each to the correct set of objects.
  3. Use one-to-one correspondence to compare sets and identify more, fewer, enough or too many.
  4. Copy, continue and create repeating patterns using colours, shapes and sounds.
  5. Identify and name 3D solids and 2D shapes and describe their position using words such as on, under, beside, in front and behind.
  6. Compare objects using direct comparison for length, height, weight and capacity.
  7. Sequence daily events using the language of time: morning, night, first, next, last, before and after.
  8. Recognise Irish coins and use one coin to match a price in a role-play shop.
  9. Count forwards and backwards from 0 to 10 and solve simple problems involving one more or one less.
  10. Collect and organise class data using real objects and simple picture graphs, then answer questions about more, fewer and most.
