Common Core Standards: 3.NBT.2, 3.NBT.1, 3.MD.1, 3.MD.2
Josh’s apple weighs 93 grams. His pear weighs 152 grams.
What is the total weight of the apple and the pear?
Use the standard algorithm to compose larger units once.
Bag A has 266 grams of beans, and Bag B has 158 grams of beans.
Use our place value charts and disks to figure out how many grams of beans we have altogether.
For bag B, put 8 ones disks in the ones column, 5 tens disks in the tens column, and 1 hundreds disk in the hundreds column.
For bag A, place 6 ones disks, 6 tens disks, and 2 hundreds disks in respective columns.
Move the disks to add 266 grams to 158 grams.
