Addition and Subtraction-TEKS: 3.2C, 3.4A, 3.4B, 3.4C, 3.5A, 3.7B
Addition and Subtraction. These plans are for 17 days of instruction. In this unit, students begin working with estimation. The use of number lines and place value relationships from Foundations of Number will help them with estimation. One and two step problem involving addition and subtraction are practiced using strategies such as place value, properties of operations and different pictorial representations. This unit also practices counting a collection of coins.
Each day contains objective, learning targets, materials, whole class teaching activity, guided math activity and closure with an exit ticket and answer key for most days.
Whole Class teaching in this unit contains:
KWL (Preview Assessment)
Math Huddle (Math Talk)
Mini Lessons (Connection, Teaching Point, Active Engagement and Link to Ongoing Learning)
Games in this unit include:
Estimation Task Cards
SCOOT:
Counting a Collection of Coins, Find the Perimeter
SCOOT Extensions:
Counting a Collection of Coins and Subtracting Some, Find the Missing Side Perimeter
Word Problem Puzzles
This unit is designed to print and go! . I keep mine in a binder. You can put each day and all of the materials for that day in one sheet protector.
I hope this unit helps you get started with Guided Math- you can’t beat $1.17 per day for a complete unit!







When teaching 3.6D, focus on finding the rectangle and relate it to the area model. A great way to start is by doing a math huddle. This year we are trying this one. We are using the one on the right, but have the one on the left just in case the groups get really stuck! Give the kids the problem on the first day of instruction- without teaching them how to do it! Let them use what they know about area from the previous units to come up with a strategy. Let them share what they are doing!
