## How To Estimate Weight: Activity for Children 5-7

Here is a simple activity to do with your child that will help develop their critical thinking skills for math and science.

**Tools and Supplies**

- Scale – a bathroom scale works great.
- Various objects to weigh, such as books, toys, a bag of flour, sack potatoes or onions, boxes of breakfast cereal, family members
- Paper and pencil

**Procedure**

- Have your child pick out two items such as a five pound bag of sugar and a ten pound bag of potatoes and have him decide which weighs the most. Demonstrate how to use a scale to weigh the items. If the scale is not digital, your child will need to look straight down at the scale to get a correct reading. Have him/her record the weights.
- Then, have him/her pick out several more items and ask him/her to estimate how much each weighs. Have him write his estimates, then weigh the objects. Discuss the accuracy or inaccuracy of the estimates and continue the activity with more objects.
- Finally, have your child estimate their own weight and the weight of other family members. You can extend the activity by having them estimate how many bags of flour or sacks of potatoes would be equal to their own weight.
