Learning Objective Name __________________________ Today, we will put objects1 in groups of ten. 1 things you can hold, touch, or see CFU What are we going to do today? What are objects? Activate (or provide) Prior Knowledge Skip counting is counting by numbers that are not one. Skip count to 100 by tens. 10 , 20 , 30 , 40 , 50 , 60 , 70 , 80 , 90 , 100 How many balls is the train carrying? 33 Train 1: 10 Train 2: 10 25 CFU Teacher reminds students of skip counting and counts the number of balls train 1 is carrying. Students skip count to 100 by tens and count the number of balls train 2 is carrying. Students, you already know how to skip count by tens. Today, we are going to skip count objects by ten after we put the objects in groups of ten. DataWORKS Educational Research (800) 495-1550 • www.dataworks-ed.com ©2011 All rights reserved.
