**Can they count to 100… until they hit 39?
A targeted Year 1 maths intervention for children who lose the counting sequence when starting from an unfamiliar number, counting backwards or crossing a multiple of ten. A quick baseline identifies the gap and routes the child to the right 10-minute session — so you’re not just giving them more counting practice.
No planning required — designed to be picked up and used by a teacher or TA
Counting to 100 is part of the Piece Together 10-Minute Maths Catch-Up series. It is designed to be picked up and delivered by a teacher or TA with minimal preparation, with a short baseline assessment showing exactly where to begin.
The six sessions develop:
counting forwards within 20
counting backwards within 20
counting forwards across a ten
counting backwards across a ten
starting from any given number to 100
flexible, independent counting and explanation
Children move from concrete and visual representations towards increasingly mental understanding, with explicit links between quantity, numerals, tens and ones, number tracks and the hundred square.

**Can they make 14… but not explain why it’s bigger than 12?
A targeted Year 1 intervention for children who can recognise or make numbers to 20 but are less secure with quantity, teen-number structure, number-line position or comparison. The baseline helps pinpoint the exact gap and directs you to the most useful 10-minute session.
No planning required — designed to be picked up and used by a teacher or TA
Numbers to 20: Represent & Compare is part of the Piece Together 10-Minute Maths Catch-Up series. It is designed for short, focused intervention with a teacher or TA, using a baseline assessment to identify the precise gap and route the child to the right starting point.
The six sessions develop:
recognising structured quantities and linking them to numerals
representing teen numbers as 10 and some more
connecting concrete, pictorial and symbolic representations
linking quantity and magnitude to position on a 0–20 number line
comparing numbers using more, fewer, less, greater, smaller and equal
ordering numbers and choosing a representation to justify thinking
The pack moves children from seeing and making quantities towards explaining and comparing numbers more independently, with explicit mathematical language throughout. The progression runs from structured recognition through teen-number structure, representation, magnitude and comparison.

**Can they tell you what comes after 39… but not what one more than 39 is?
A targeted Year 1 intervention for children who can often count in sequence but don’t yet fully understand the one-more/one-less relationship — particularly across tens boundaries. Start with the baseline, identify the gap, then go straight to the appropriate 10-minute session.
No planning required — designed to be picked up and used by a teacher or TA
One More & One Less is part of the Piece Together 10-Minute Maths Catch-Up series. It is designed for short, focused intervention with a teacher or TA, using a baseline assessment to identify the precise gap and route the child to the right starting point.
The six sessions develop:
finding one more within 10
finding one less within 10
finding one more and one less for teen numbers
crossing 9 ↔ 10 and 19 ↔ 20
finding one more and one less to 100, including across a tens boundary
flexible reasoning with neighbouring numbers and explanation
The pack keeps the focus on the fact that the quantity changes by exactly one, even when the numeral changes noticeably at a tens boundary. Children connect counters, ten-frames, number tracks, hundred squares and tens-and-ones structure to the numerical relationship.

Three common Year 1 number gaps. Three targeted interventions. One ready-to-use catch-up bundle.
Designed for children who need extra support with counting to 100, representing and comparing numbers to 20, or one more and one less. Each pack starts with a short baseline that identifies where the difficulty lies and routes the child to the right 10-minute intervention session.
No planning required — designed to be picked up and used by a teacher or TA
This bundle brings together three Piece Together 10-Minute Maths Catch-Up packs:
Counting to 100
Numbers to 20: Represent & Compare
One More & One Less
Each pack begins with a short Starting Point Assessment to help identify the child’s exact gap and route them to the most appropriate session, rather than automatically starting at Session 1.
The interventions are designed to be easy for a teacher or TA to pick up and use, with short, focused sessions that build understanding through concrete resources, visual representations, mathematical language and increasingly independent thinking.
Across the three packs, children develop confidence with:
counting forwards and backwards
starting a count from different numbers
crossing multiples of ten
recognising and representing quantities to 20
understanding teen numbers as 10 and some more
comparing and ordering numbers
using number lines and structured representations
finding one more and one less
crossing tens boundaries when finding neighbouring numbers
explaining their mathematical thinking
Each pack includes
Starting Point Assessment
clear diagnostic routing
6 structured 10-minute intervention sessions
adult prompts and mathematical vocabulary
practical and pictorial representations
CORE and IF TIME activities
quick checks
progress recording using I / R / P / N
Exit Check
reusable printable maths resources
The bundle is ideal for:
Year 1 / KS1 intervention, catch-up, targeted TA support, small groups and 1:1 work.
All three packs are designed in a print-friendly greyscale format and follow the same consistent structure, making them easy to use as part of a wider intervention approach.

The six-session sequence moves from using known bonds to 10 as a bridge, through seeing 20 as two tens and organising bonds systematically, before progressing to missing parts, related facts and flexible recall.
The baseline also checks whether the child is actually ready for this intervention. If bonds to 10 are insecure, the pack routes them back to the Number Bonds to 10 intervention. If teen-number structure is insecure, it directs the adult towards prerequisite number work instead.
Each session includes a clear objective, equipment, teaching prompts, Make the Link language, core practice, optional extension, quick assessment and guidance on what to teach next.
Suitable for:
Year 1 maths intervention, KS1 catch-up, SEND support, small-group work, 1:1 intervention and targeted addition and subtraction work.
Designed as a follow-on to Piece Together: Number Bonds to 10.
