Math Update

In math we will be learning about measurement and negative numbers.

You can expect to see work that provides practice measuring length, weight, and temperature.

Vocabulary to know:
temperature: A measure or how hot or cold something is.
integers: The set of whole numbers, their opposite negative numbers, and zero.
positive number: A number that is greater than zero.
negative number: A number that is less than zero.

A challenging area for fourth graders is answering questions like this:
Which temperature is greater -2 degrees Fahrenheit or -5 degrees Fahrenheit?

A way to help your child with this is to think of a thermometer as a vertical number line. Temperatures above zero are positive numbers. Temperatures below zero are negative numbers. On a thermometer locate -2 and -5.
As you move UP a thermometer, temperatures increase.

Learning about measurement and negative numbers will help students understand situations in the real world.
