I developed this game to give my students another way to practice facts by starting with the whole and going to the parts. Sometimes you will find an activity that requires children to give all the basic facts for a given sum. Going from the whole to the parts stumps some students because it is not the way they practice. (flashcards, worksheets, or board races) Using this game has given my students more practice with this type of activity without using worksheets.
The common core standards are:
CCSS Math Content.1.OA.C.5
Add and Subtract to 20
CCSS Math Content. 2.OA. B.2
Fluently add and subtract through 20 using mental strategies. By the end of grade 2, know all sums of one digit numbers.
This activity requires children to match the sum on umbrellas with the facts on umbrellas. There are five facts for each sum. Children can challenge each other to see who can complete the activity the quickest. They can use this activity in much the same way as you play concentration. Finally they can play as an individual. My students have made up more ways to play. They are not listed in the directions, but I am sure your students will use their imaginations as well.
Included in this activity is a title page, directions for playing and for assembly, a score sheet, 8 umbrellas, and 40 raindrops.
