### Add a single digit to a 3-digit number

Activities to help with adding a single digit to a multiple of 100. Base ten blocks are a useful way of showing these numbers. Activities are of increasing difficulty: at first the tens are not crossed (e.g. 345 + 2), leading on to crossing the tens (345 + 7). Timed challenges are available once confidence is high.
