Students will learn how to estimate differences. Students will round the top and bottom number in a subtraction problem (up to 3 digit numbers), and then subtract them to find the estimate.
This lesson will also include the information on creating a word wall or flip book for the Addition and Subtraction word keys found in word problems.
This PowerPoint includes the components of a Direct Instruction lesson. Among other things, it includes a student friendly objective, purpose, vocabulary development, example/non-example, guided practice, and independent practice in the form of a writing prompt.
