**Three common Year 1 number gaps. Three targeted interventions. One ready-to-use catch-up bundle. ** A practical Year 1 maths intervention bundle for children who need extra support with early number and place value. 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. Piece Together Simple. Targeted. Teacher-ready. If the bundle is useful in your classroom, a quick TES review really helps other teachers find the Piece Together range.

**Can they count to 100… until they hit 39? A simple, targeted Year 1 maths intervention for children who can count in familiar sequences but lose confidence when starting from an unfamiliar number, counting backwards or crossing a multiple of ten.** 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. Included in the pack Starting Point Assessment with I / R / P / N recording clear diagnostic routing to the appropriate session 6 structured 10-minute intervention sessions adult prompts and mathematical vocabulary CORE and IF TIME tasks quick checks and progress recording Exit Check to measure progress large printable 0–20 number track full-size 1–100 hundred square optional 0–99 hundred square structured dot cards numeral cards tens-and-ones resources Designed for Year 1 / KS1, small-group or 1:1 catch-up, intervention sessions and targeted TA support.

Can they make 14… but not explain why it’s bigger than 12? A targeted 10-minute Year 1 intervention for children who need support with number sense, teen-number structure, representation, magnitude and comparison to 20. 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. Included in the pack Starting Point Assessment with I / R / P / N recording clear diagnostic routing to the correct session 6 structured 10-minute intervention sessions adult prompts and mathematical vocabulary CORE and IF TIME tasks quick checks and progress recording Exit Check to measure progress blank and fully numbered 0–20 number lines optional 0–20 number track numeral cards 0–20 structured dot / subitising cards large printable double ten-frame part-whole template Designed for Year 1 / KS1, small-group or 1:1 catch-up, intervention sessions and targeted TA support.

Can they tell you what comes after 39… but not what one more than 39 is? A targeted 10-minute Year 1 intervention for children who need support understanding one more and one less, including crossing tens boundaries. 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. Included in the pack Starting Point Assessment with I / R / P / N recording clear diagnostic routing to the correct session 6 structured 10-minute intervention sessions adult prompts and key mathematical vocabulary CORE and IF TIME tasks quick checks and progress recording Exit Check to measure progress large printable 0–20 number track full-size 1–100 hundred square optional 0–99 hundred square One Less | Number | One More reasoning mat large printable double ten-frame focused numeral cards Designed for Year 1 / KS1, small-group or 1:1 catch-up, intervention sessions and targeted TA support.

A free Year 1 number bonds to 20 intervention pack with a baseline assessment, six structured 10-minute sessions, printable resources and an exit check. This follow-on Piece Together intervention is designed for pupils who are ready to move beyond bonds to 10 and develop secure understanding of number bonds to 20. The pack covers bonds to 20, missing parts and related addition and subtraction facts, while also reinforcing teen-number structure and the relationship between bonds to 10 and bonds to 20. It is aligned with the England Year 1 Addition and Subtraction curriculum. Included: 5-minute starting point assessment Clear diagnostic routing Six 10-minute teaching sessions Session progress record Bonds-to-10 prerequisite check Teen-number structure Double ten-frame work Systematic bonds to 20 Missing-part problems Related addition and subtraction facts Flexible recall and reasoning Exit assessment Printable part-whole mat Large double ten-frame Numeral cards Two child recording tables Adult reference sheet 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.
