Use these sheets to help students improve their fact fluency. Students focus on mastering one strategy at a time. I currently use these as timed tests (aka ‘mad minutes’). I have also used these as review worksheets for extra practice.
8 strategies included:
• Plus Zero / Plus One
• Count On (+1, +2, +3)
• Tens Partners
• Doubles + 1
• Turn Around
• Plus 10
• Plus 9 (See 9, think 10.)
