A Siberian tiger sleeps as much as 15 hours a day, or 105 hours per week.
About how many hours does a tiger sleep in a year?
Step 2 - Multiply by ones
Step 3 - Multiply by tens
Step 4 - Add partial products
Step 1 - Estimate: 105 × 52 → __________ × __________ = __________
Step 2 - Multiply by the ones.
→ 105 × 2 ones = __________ ones (first partial product)
Step 3 - Multiply by the tens.
→ 105 × 5 tens = __________ tens or __________ ones (second partial product)
Step 4 - Add the partial products.
__________ + __________ = __________ (final product - answer)
