Basic operations – Using the four digits 2, 0, 1 and 6 and the four operations (addition, subtraction, multiplication and division) can you make equations that equal all the numbers from zero to 20?
- Which multiplication tables do you know best?
- What do all the multiples of 2 and 4 and 8 have in common?
- How do you know if a number is divisible by 5 or 10?
- Write down all the multiples of 3 in order and see if you can determine something that they all have in common (clue – add the digits together).
Screenshots of Write Sums – an application for iPod Touch and iPhones
While most of the class have been starting a unit of work on Algebra, some students need to practise their basic drills. They have been enjoying using the iPod with this application, “Write Sums”. The Lite version has three different levels of difficulty and the choice of a short game (10 questions) or a long game ( 25 questions). The script recognition is pretty good, although it does get confused between “0” and “6” from time to time, which can be frustrating for the students. But it also teaches them to write neatly! This is a tactile game that they believe has improved their skills with basic operations.
Jonathon Riley has written about “The Top 10 iPod Touch Apps to Use in Maths Class“, which are all free apps. Not all of them are suitable for middle years students (iFormulas and Quick Graph are probably for older students), but they are recommended for hand-held practise.
