In this PowerPoint place value models are used to show students how to write two digit numbers in expanded form.

This lesson demonstrates three different strategies for finding a number that is 10 more, 1 more, 10 less and 1 less than a given number. This presentation uses place value models and a hundreds chart. It also demonstrates the use of basic addition. I always like to model several strategies so my students can pick which strategy works best for them. I hope you enjoy this lesson!

In this PowerPoint students will learn about numerators and denominators. They will learn about halves, thirds and fourths. There is a quiz at the end to review. This PowerPoint would be great for an Interactive Whiteboard!

In this interactive PowerPoint presentation, students are introduced to Mr. and Mrs. Alligator, who happen to be very hungry! The alligators are presented with two groups of place value blocks, and students have to guess which way the alligator will go. At the end their is an interactive quiz in which students are provided feedback whether their answer is incorrect or correct. This PowerPoint is filled with animation that will captivate your students' attention.

This PowerPoint was designed to review material covered in Chapter 2 of the Scott Forseman Addison Wesley math series for First Grade. It reviews both addition and subtraction concepts. This PowerPoint was designed to work with Quizdom Software.

This PowerPoint was designed to go with Scott Foresman Addison Wesley 1st grade 8-4 Lesson. This presents the tricky concept of showing a number two ways with place value models. For example, 45 could be shown as 40 + 5 = 45 or 30 + 15 = 45. This presentation is animated and shows carrying a ten back to the ones place and breaking it apart.
