The document provides two word problems to estimate the total weight of hippopotamuses being shipped to a new zoo location and the number of computers a school can purchase with $4300. For the first problem, there are 6 full-grown hippos weighing an average of 5710 pounds each and 2 half-grown hippos, so the total weight is estimated to be around 42,000 pounds. For the second problem, computers cost $799 each and rounding to the nearest $800, the school can buy approximately 5 computers.

1. You will use what you know
about estimation to solve the

2. A zoo wants to estimate how much it would
cost to ship some hippopotamuses to a new
location. An adult hippopotamus weighs an
average of 5710 pounds. The zoo has 6 full-
grown hippos and 2 half-grown hippos.
Estimate the total weight of these
hippos. Write your estimate and
the estimated answer.
Problem 1
Do NOT advance to the next slide until you’ve tried
the problem on your own in your notebook.

3. 1. The zoo has 6 full-grown hippos and 2
half-grown hippos. So, altogether that
makes about 7 full-grown hippos.

2. We were told that each hippo weighs an
average of 5710. If I were to find the exact
answer, I would have to solve: 5710 x 7

2. We were told that each hippo weighs an
average of 5710. If I were to find the exact
answer, I would have to solve: 5710 x 7
3. We were asked to estimate, so:
5710 x 7 ≈ 6000 x 7 = 42,000

The hippos weigh about 42,000 pounds.

7. A school has $4300 to spend on new
computers. Each computer costs $799.
Estimate the number of computers the
school can buy.
Write your estimate and the
estimated answer.
Problem 2
Do NOT advance to the next slide until you’ve tried
the problem on your own in your notebook.

8. 1. The school has $4300 to spend on
computers, and each computer costs
$799. If I were to find the exact answer, I
would have to solve: $4300 ÷ 799

2. We were asked to ESTIMATE, so we will
estimate the problem written in red
above:
1. The school has $4300 to spend on
computers, and each computer costs
$799. If I were to find the exact answer, I
would have to solve: $4300 ÷ 799
ESTIMATE to the closest multiple of 8.
You must ROUND 799, so it will become 800.
Click next.
4300 ÷ 799 ≈ 4000 ÷ 800 = 5

10. HOW-TO SOLVE
2. We were asked to ESTIMATE, so we will
estimate the problem written in red
above:
4300 ÷ 799 ≈ 4000 ÷ 800 = 5
1. The school has $4300 to spend on
computers, and each computer costs
$799. If I were to find the exact answer, I
would have to solve: $4300 ÷ 799
Don’t forget to
write it in a
sentence.
The school can buy 5 computers..
