Beanie Toss to 100 Freebie

Here's a freebie that's perfect for Day 100 or any day of the year that your students need to practice adding tens.

Plus, it works toward these Common Core Standards:

1.NBT.C.4 Add within 100, including adding a two-digit number and a one-digit number, and adding a two-digit number and a multiple of 10, using concrete models or drawings and strategies based on place value, properties of operations, and/or the relationship between addition and subtraction; relate the strategy to a written method and explain the reasoning used. Understand that in adding two-digit numbers, one adds tens and tens, ones and ones; and sometimes it is necessary to compose a ten.

1.NBT.C.5 Given a two-digit number, mentally find 10 more or 10 less than the number, without having to count; explain the reasoning used.

1.NBT.C.6 Subtract multiples of 10 in the range 10-90 from multiples of 10 in the range 10-90 (positive or zero differences), using concrete models or drawings and strategies based on place value, properties of operations, and/or the relationship between addition and subtraction; relate the strategy to a written method and explain the reasoning used.

2.NBT.B.8 Mentally add 10 or 100 to a given number 100–900, and mentally subtract 10 or 100 from a given number 100–900.

I have a lot of beanie babies in my classroom, but simple bean bags would suffice.  (Click the bean bag image below to purchase on Amazon.)

The children simply toss the bean bags from behind the line and record their score!  If the bag lands in the center circle, they score 30 points!  If the bag lands in the outer circle, they score 10 points.

Yep, it's that simple, and guaranteed to give you loads of giggles!  Click the image to download your freebie!
