This interactive PowerPoint lesson is designed to get your students thinking about estimation. The first 2 slides define what estimation is and is not. The following slides show pictures of groups of objects with three estimation choices. Upon click, the slide circles the correct answer. The packet also includes two independent practice worksheets. This activity is designed for kindergarten through first grade and covers numbers from 0 to 100.
Packet includes a one page mini assessment.
Making the PowerPoint Interactive:
Have students make their guesses and put that number in their heads. (I usually have students point to their brains when they have their number in their heads.)
Once all students have made an estimate, ask several students to share out which number they thought was closest and why. Then think aloud as you solve the problem. When the class has agreed upon an estimate, click to circle the correct answer.
Then continue through the remaining slides. I have found it helpful to allow students to turn and talk to a neighbor to discuss their estimates. Students are encouraged to challenge each other by asking questions like “Why do you think that?” or “How did you figure that out?”
