Last week my firsties were working on ? number more and ? number fewer. This was very difficult for them to do for some reason. So I made up some Halloween math ladders to help them with this concept. The packet has 5 pumpkin worksheets dealing with fewer numbers and 5 ghost worksheets dealing with more numbers. There are also answer keys for all 10 worksheets. This packet also works with number patterns too. It's available at both my TpT store and TN store for $1.00.
For Manic Monday I have a freebie: 1 fewer pumpkin worksheet and 1 more ghost worksheet.
