Number Sense is so important in the primary grades! Give your students extra practice with these number puzzles. Students will see the different ways to make a number (word form, addition sentence, base 10 blocks, money, pictures, ten frames, etc.) and will have to put the puzzle back together with the corresponding number.
I use these as early finisher activities, but these could also be used as a math center.
I group 2 puzzles (example: numbers 5 and 6 in a bag) together and students have to put both puzzles back together.
This is geared towards 1st grade but could be used with your second graders who need a little extra help with number sense.
