How to Estimate Weight - Have you ever seen your teachers, elders, and friends making wild guesses about a material, object, and a person? Does this make you wonder how you are so well at making such estimates? If that's what you think, here we tell you a little secret. You can make wild guesses or estimates too about the weight of objects or persons. Estimating is a skill that you will greatly need in mathematics as well as in your daily life. To make it easier for you, let's make you learn estimation starting with a grocery store. Look at the example below: You are in a grocery store, and you find your favorite golden apples there. You notice that the apples are for $1.00 a pound. This is something to keep in mind before you start filling your shopping bag. Remember you have only $2.00 in your handbag, and you can't buy more than two pounds of apples. How will you make sure you don't cross 2 pounds? Yes, you can do it with a scale, but consider that it's broken too. One strategy you can use is trying to make a mental estimation with similar objects. Use specific weight units like ounce for lighter objects, pounds for medium objects, and kilograms for heavy objects. A great selection of worksheets and lessons that helps students learn to quickly gauge accurate measures of units of mass.

#### Homework Sheets

Yes, I know the cell phone image is a bit dated.

- Homework 1 - Estimate the weight of this phone. Circle the estimated weight.
- Homework 2 - This looks like a very heavy object. I would therefore say we are looking for the largest unit possible.
- Homework 3 - Paper is very light, so I would look for the lightest unit.

#### Practice Worksheets

I did research most of the answers so that they flow with reality.

- Practice 1 - All the measures differ by units of measure. The best thing to do is to determine if the object is light or heavy.
- Practice 2 - If it is heavy, we will get rid of the light units.
- Practice 3 - If the object is light, we will get rid of the heavy units.
