1 Sorting and Numbers to 5, Re-anchor 10 lessons · about 10 hours

Settle the class into the maths-box routine and re-secure sorting by a rule, one-to-one matching, and 0 to 5 as amounts, numerals and ordered sets. Everything stays oral and play so every pupil starts the year feeling like a mathematician.

  1. 1 Back to the Maths Box, Sorting by Colour
  2. 2 Same Things, New Rule, Sorting Two Ways

2 The Numbers 6 to 10 16 lessons · about 16 hours

The heart of the Senior Infants year: each of 6 to 10 is met, made, counted, written and found in the child's own world, then the whole family is ordered, compared and seen at a glance. Every number is built in egg boxes, frames, fingers and beads before its numeral is traced.

  1. 11 The Number 6, the Egg Box
  2. 12 Writing 6
  3. 13 The Number 7, a Rainbow of Colours
  4. 14 Writing 7 and Lining up 0 to 7

  16. 26 The Number Show, 6 to 10 in Review
3 Ten as Our Friend, Part-whole and Bonds to 10 14 lessons · about 14 hours

Numbers to 10 become flexible: every set can be broken into parts and put back together, six to nine are seen as five and a bit, and ten becomes the friend every number wants to make. It stays oral and concrete, combining and partitioning language only, with symbols saved for 1st Class.

  1. 27 Snap, a Whole Breaks Into Parts
  2. 28 All the Ways to Break 5
  3. 29 Five on One Hand

  14. 40 Ten Is Our Friend, Module Review
4 Counting on, to 20, Forwards and Back 10 lessons · about 10 hours

The count stretches to 20, forwards, backwards and counting on from any start. Numerals to 20 are met, pegged and ordered on the line but nothing is written beyond tracing: this is oral counting made strong, with the number line as the picture that holds it together.

  1. 41 Off We Go to Twenty, Counting Past Ten
  2. 42 Eleven and Twelve, Ten and Some More
  3. 43 The Teens on the Line, 13, 14 and 15

  7. 47 Zoom to the Moon, Counting Back
  8. 48 The Missing Number, Before, After and Between
  9. 49 Guess Then Count, the Big Handful
  10. 50 The Counting Show to Twenty, Module Review
5 Patterns, Repeat, Grow and Describe 10 lessons · about 10 hours

Repeating patterns come back stronger, read aloud, copied, extended, fixed and carried into new materials, and patterns that grow by one more each time arrive for the first time. Everything is built in cubes, beads, claps and stamps, pushing from what comes next towards what is the rule.

  1. 51 Pattern Hunt, Patterns All Around Us
  2. 52 Copy My Pattern
  3. 53 What Comes Next?
  4. 54 Body Patterns, Clap, Stamp and Hop
  5. 55 New Pattern Families, AAB and ABB

  8. 58 Pattern Doctor, Spot the Mistake
  9. 59 Growing Patterns, Peter's Hammers
  10. 60 The Pattern Party, Module Review
6 Shape, Sorting, Building and Shape Movements 14 lessons · about 14 hours

Solids come first, held, rolled, stacked and printed, and flat shapes are discovered living on their faces. Then shapes start to move, turning, sliding and flipping without changing what they are, and position words say exactly where things sit. Mostly hands and eyes, with the interactive kept for sorting and picture-building.

  1. 61 The Feely Bag, Meeting the Solids Again
  2. 62 Roll or Slide? the Ramp Test
  3. 63 Stack and Build, the Tower Test
  4. 64 Solid Hunt, Shapes in Our World
  5. 65 Face Prints, Flat Shapes Live on Solids
  6. 66 The Circle and the Square
  7. 67 The Triangle and the Rectangle
  8. 68 Shape Pictures, Build It from Shapes
  9. 69 Shape Hunt in the Yard
  10. 70 Turning Shapes, Round and Round
  11. 71 Slide It, Flip It
  12. 72 Where Is Teddy? Position Words
  13. 73 Follow the Way, Journeys and Turns
  14. 74 The Shape Show, Module Review
7 Measures, Compare and Order 12 lessons · about 12 hours

Direct comparison grows into ordering three and more objects, and comparing by eye grows into counting non-standard units, cubes, handspans, steps and cupfuls. The balance settles the arguments our eyes cannot, including the surprise that big is not always heavy.

  1. 75 Long and Short, Line Them up
  2. 76 The Three Bears, Ordering by Size
  3. 77 Tall and Short, How Tall Are We?
  4. 78 How Many Cubes Long?
  5. 79 Handspans and Giant Steps
  6. 80 Heavy and Light, the Feel Test
  7. 81 The Balance Decides, Big Is Not Always Heavy
  8. 82 Full and Empty
  9. 83 Which Holds More? Cupfuls Count
  10. 84 Guess Then Check, Measuring
  11. 85 Wide and Narrow, Thick and Thin
  12. 86 The Measuring Show, Module Review
8 Time, Days, Seasons and How Long Things Take 10 lessons · about 10 hours

Time at Senior Infants is lived, not read from a clock: the day gets its order, the week gets its seven names, the year turns through four seasons, and how long becomes something to feel and compare with sand timers and counted claps. The clock face waits for 1st Class.

  1. 87 First, Next, Last, Our Day in Order
  2. 88 Day and Night
  3. 89 The Days of the Week
  4. 90 Today, Yesterday and Tomorrow
  5. 91 School Days and Home Days
  6. 92 The Seasons, the Year Goes Round
  7. 93 Season Detectives, What We Wear, What We Do
  8. 94 How Long Does It Take? the Sand Timer
  9. 95 Which Takes Longer?
  10. 96 The Time Show, Module Review
9 Money, Coins in Our Shop (to 10c and 20c) 8 lessons · about 8 hours

The shop corner opens for real business: money is for swapping, the little coins 1c, 2c, 5c and 10c get names, faces and worths, and prices to 10c are read from tags and paid coin by coin in play, with the 20c coin met at the end. Everything is buying, selling and counting cents aloud, no written sums.

  1. 97 The Shop Corner Opens, What Is Money for?
  2. 98 Meet 1c and 2c
  3. 99 The 5c Coin, Five Cents in One
  4. 100 The 10c Coin, Ten Cents in One
  5. 101 Price Tags, Pay Just Enough
  6. 102 Two Coins in My Purse
  7. 103 Meet the 20c Coin
  8. 104 Grand Shop Day, Module Review
10 Fair Shares, Halves in Play 6 lessons · about 6 hours

Halving arrives the way infants meet it in life, sharing fairly between two. One thing is cut into two fair parts, paper folds into matching halves, and little sets deal out one for you, one for me, all in the language of fair and not fair. No fraction symbols and no quarters, just halves you can hold.

  1. 105 Fair or Not Fair?
  2. 106 Half a Pizza, Two Fair Parts
  3. 107 Fold It in Half, Matching Halves
  4. 108 Half of a Little Set
  5. 109 Halves Everywhere, Half Full, Half Way
  6. 110 The Fair-shares Picnic, Module Review
11 Our Class Asks Questions, Surveys and Pictograms 10 lessons · about 10 hours

The year closes with the class finding things out for itself: ask a question we can count, collect the answers, sort and count them, and show them so anyone can read them, cube towers first, then tally marks, then pictograms where one picture means one answer. Reading the chart matters as much as building it.

  1. 111 What Do We Want to Find Out?
  2. 112 Sort the Answers, Count Each Set
  3. 113 Cube Towers That Tell
  4. 114 A Mark for Each, the Tally Chart
  5. 115 One Picture for Each, Our First Pictogram
  6. 116 We Are the Chart, a Living Pictogram
  7. 117 Survey Day, Ask, Count, Tell
  8. 118 Data Walk, Counting the Yard
  9. 119 How Many More? Reading the Rows
  10. 120 Our Class Found Out, Module Review

What pupils learn

This course builds a strong foundation in early mathematics for senior infants through practical, play-based activities. Students develop number sense to 20, master counting forwards and backwards, explore part-whole relationships and bonds to ten, and investigate repeating and growing patterns. They sort and combine 2D and 3D shapes, compare measures of length, weight and capacity, tell time through daily routines and seasons, handle coins up to 20c in shop scenarios, share equally using halves, and collect and represent data in simple pictograms and tallies. Its distinctive emphasis on concrete, sensory experiences and real-world connections makes abstract concepts meaningful and memorable.

By the end of the course, pupils can

  1. Sort objects by one or two attributes such as colour or size and explain the rule used.
  2. Count, read, write and order numbers from 0 to 20 accurately.
  3. Identify and complete repeating patterns including AB, AAB and ABB sequences and growing patterns.
  4. Recognise and name 2D shapes and 3D solids, describe their properties and combine them to make pictures or models.
  5. Use non-standard units to compare and order objects by length, weight and capacity.
  6. Identify and sequence the days of the week, seasons and daily events using words such as first, next, yesterday and tomorrow.
  7. Recognise 1c, 2c, 5c, 10c and 20c coins and use them to pay exact prices up to 20c in role-play shopping.
  8. Find and name halves of shapes, sets of objects and quantities using the language of fair shares.
  9. Collect data through simple surveys, record results in tally charts and pictograms, and answer questions such as ‘how many more?’.
