To use base ten blocks to model
432 is 400 and what
renaming 432 = 3 hundreds + 13 tens + 2 432 is 300 and what
ones and then 3 hundreds + 12 tens + 12
ones

• Do renaming
• Carry out the operations
These are done separately.
200 – 18
• Rename 200 as 100 + 90 + 10
• Now subtract 10 and 8 from 90 and 10
2,476 x 3
• Multiply to get 18, 210, 1200 and 6,000
• Now add the partial products
