This is a lesson modified from the PBS lesson at https://www.pbs.org/wgbh/nova/teachers/activities/3211_megafloo.html
I've added some supports for younger students and removed some more complicated vocabulary.
Read the lesson attached and answer the questions as you go.
Move each example measurement into the category of what it is measuring.

During one of the most recent ice ages, about _________ years ago, ice sheets thousands of feet thick covered what is now southern British Columbia.
A lobe from the Cordilleran ice sheet crept into the Idaho panhandle and blocked the Clark Fork River with an ice dam. How high was the ice dam?
Water melting from the glacier further north backed up behind the ice dam, forming Glacial Lake Missoula. It covered ____ square kilometers of western Montana.
The climate warmed, weakening the ice dam's base. What happened when the ice dam could no longer resist the increasing water pressure?
As water rushed westward from the ice dam, it carved out the Channeled Scabland. What notable geographical feature did it create?
Rushing water also created present-day Dry Falls. What are its dimensions?
At the flood's height, certain geographical shapes in Camas Prairie were formed. What are they?
The water tore across the Camas Prairie at a high speed. What was this speed?
Despite its incredible nature, J Harlen Bretz theorized the flood happened ...
