Hi! This is a worksheet meant to help teach Fact Families or give your kiddos a little extra practice! This would be a great page to run for morning work! Run it one sided and use it for two days or run double sided and do it in one day! I left one box blank for them to create their own fact family--an easy way to differentiate and let those kids that BEG to use big numbers show you what they can do! You'll see the equal sign both at the beginning and end of the number sentences. Having the equal sign at the front of a number sentence is a new skill for first graders! Thank you for your feedback/comments. ENJOY!
