Read the rule on the banner, such as CATCH THE PRIME NUMBERS. 2. Drag Pip left and right to catch the numbers that fit. 3. Dodge the numbers that do not fit, and do not let a right one fall past. 4. Watch for the RULE CHANGE banner, then the final rush. ## What your child learns It is a square numbers game and a prime numbers game, with multiples and factors as warm-ups. These are the KS2 skills it practises. - Prime numbers - Square numbers - Multiples and factors - Odd and even numbers - Quick mental calculation Real examples from the game: CATCH THE PRIME NUMBERS**2, 3, 5, 7, 11, 13 ...** CATCH THE SQUARE NUMBERS**1, 4, 9, 16, 25, 36 ...** CATCH THE FACTORS OF 36**1, 2, 3, 4, 6, 9, 12, 18, 36** ANSWERS EQUAL TO 24**6 × 4, 48 ÷ 2, 30 − 6** ## Levels and difficulty A run is three 30-second rounds. Round 1 is an easy rule such as even numbers or multiples of 5, and round 2 keeps the rule with numbers that sit closer together. Round 3 changes to a hard rule, such as primes, squares or factors of 24, then a five-second final rush ends the run. Pip moves your child up when they are ready and eases off when they struggle. Each run is short and focused, so it fits before school or homework. ### Every level, in the free Pip app Pip Catch is free in the app, with every level and saved progress. [Download Pip on the App Store](https://apps.apple.com/app/pip-11-practice/id6775690698) [Get Pip on Google Play](https://play.google.com/store/apps/details?id=com.pip11plus.app) [Available at Amazon Appstore](https://www.amazon.co.uk/dp/B0HKGJ4HTP) ## Tips for parents and teachers - Learn the primes to 20 by heart first: 2, 3, 5, 7, 11, 13, 17 and 19. - Point out that 1 is not prime and 2 is the only even prime, the two catches children miss most. - Square numbers are easier once your child knows 1 × 1 to 12 × 12, so pair this with a times tables game. ## Pip Catch FAQs **Is Pip Catch free?** Yes. Pip Catch is free in the Pip app, with every level, and the one-minute demo here is free too. **Can I play Pip Catch online?** Yes, for one minute. Press Play above to try the demo in your browser with nothing to install, then carry on in the Pip app. **What age is Pip Catch for?** Years 3 to 6, within KS2 (ages 7 to 11). The game adapts, so it suits a wide range of children. **Does Pip Catch work on iPad?** Yes. The demo works in Safari on iPad, and the full game is in the Pip app for iPad, iPhone, Android and Fire tablets. **What is a prime number in KS2?** A prime number has exactly two factors, 1 and itself, so 7 is prime and 9 is not. Children meet primes and square numbers in Year 5. **Is 1 a prime number?** No. 1 has only one factor, so it is not prime, and Pip Catch counts a caught 1 as wrong on a prime round. ## More games like this More maths games in the arcade, plus free practice pages.
