Are you after regular mathematics practice?
You are teaching how to record subtraction and think that it is the inverse of addition so is easy! But, when you are showing 77 subtract 16, you don’t recall how to explain why you started with 7 minus 6 instead of 70 minus 10, right? This worksheet explains for 6 to 12 year olds how subtraction without decomposition works for two digit numbers with plain and simple examples and exercises.
- Shows with examples what to do, for learners to be confident that they are capable mathematicians
- Helps them learn how to partition numbers into tens and ones, for learners to master the role of place value in subtracting
- Provides instructions to partition in columns, for helping learners quickly figure out the strategies that they prefer and work for them
- Offers a different approach to the column method of subtraction where ones are placed under ones and tens under tens, for facilitating learners' development
- Links to mental methods of subtraction by using place value, for ease of understanding subtraction
- Offers exercises in recording subtraction using partitioning in columns: subtract the tens and then the ones to form partial differences in columns and then add these partial differences, so that they can easily understand how addition works.
