The document provides instructions for estimating the total weight of hippopotamuses being shipped and the number of computers a school can purchase. It contains two word problems: 1) A zoo has 6 full-grown and 2 half-grown hippos, with an average weight of 5710 pounds. Estimating the total weight as 7 full-grown hippos at 6000 pounds each gives an estimate of 42,000 pounds. 2) A school has $4300 to spend on computers that cost $799 each. Estimating $799 as $800, the school can buy about 5 computers. The document guides the reader through solving each problem step-by-step and emphasizing estimation.

1. You will use what you know
about estimation to solve the
word problems that follow.
Solve the following 2 problems in
your notebook.

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.

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

HOW-TO SOLVE
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

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

Don’t forget to
write it in a
sentence.
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

HOW-TO SOLVE

9. HOW-TO SOLVE
2. We were told that 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 told that 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..
