Fun basic adding and subtracting activities for primary maths in Key Stage 1 KS1 (Year 1, Year 2 - Y1, Y2) or maths intervention in lower KS2 (Year 3, Year 4) children who require practice and revision of basic addition and subtraction (facts fluency, number bonds to 20, addition and subtraction up to 20, doubles, near doubles etc). In this BUNDLE there are **15 puzzle worksheets** and **36 self-checking trails**. Both are in **PDF** format. Use in Primary 1, 2 and 3 ( P1, P2 and P3) in Scotland, 1st, 2nd and 3rd Grade US, Grades 1, 2 and 3 in Canada, and equivalents. ***Both packs in this BUNDLE are also available separately:***   **[Basic Addition and Subtraction Fluency Puzzles Worksheets](https://www.tes.com/teaching-resource/basic-addition-subtraction-fluency-activities-12278565)** Designed as fun alternatives to standard worksheets to provide variety and extra practice of addition and subtraction facts beyond Year 1, including some special educational needs contexts (SEN). Students must have basic spelling ability to uncover the 4 or 5-letter hidden words that feature in these calculation puzzles (although clues can be given, of course!). Please check the detailed preview to assess if they will meet your needs. For a full list of the puzzles please the individual resource page. These puzzles work by students looking over completed calculations, hunting for errors. Students often forget or avoid checking their work so it’s great to get them carefully checking in these puzzles! Spotting common errors may help them remember to check their own work. Each puzzle contains 21 completed calculations, with 4 or 5 deliberate errors. There is a letter printed in each box, below the calculation. Students circle all the boxes containing calculation mistakes. When they have finished, they put all the letters together from the circled boxes and rearrange the letters to spell the name of an animal. If students have assembled the correct letters but find the rearranging very challenging, you can have them work in pairs or give them clues, such as the first letter of the word or a fact about the animal. The animal printed on each puzzle is for illustration purposes and is not related to the answer. **Answer Keys** are located after each puzzle. You can print them for students to self-check if required. You might want to display them instead. TIP: To save printing and to use again and again, why not laminate the puzzles and have students complete them with dry-wipe markers? Alternatively, put the sheets in a dry-erase sleeve.   **[Adding and Subtracting within 20 Write and Wipe Cards](https://www.tes.com/teaching-resource/number-bonds-to-20-11543953)** 36 self-check write and wipe trail cards to be laminated for pupils to complete with whiteboard pens or use as worksheets with a difference. Starting at the spider and working their way around in a spiral, children write each answer in the box, creating a running total. The final answer is printed next to the web in the middle of the card so they can see if they have correctly completed it. If not, children can check to see where they have gone wrong. **Separate answer keys** are also included, should you require them.   ***YOU MIGHT ALSO LIKE...*** * [**Add and Subtract within 50 Write and Wipe Cards**](https://www.tes.com/teaching-resource/number-bonds-to-50-11544133) * [**Add and Subtract 9, 10 and 11 Write and Wipe Cards**](https://www.tes.com/teaching-resource/add-subtract-9-and-11-11556042) * [**Add and Subtract Multiples of 10 Write and Wipe Cards**](https://www.tes.com/teaching-resource/addition-subtraction-multiples-of-10-11556029)   Thank you for your interest in my resources. **[FullShelf Resources](https://www.tes.com/teaching-resources/shop/FullShelf)**
