This 169 slide PowerPoint will help you teach Topic A of the Grade 4 Module 1 (Place Value of Multi-Digit Whole Numbers). My colleague and I quickly realized when we used the ELA modules last year that these lessons aren't particularly child friendly or easy to teach! We developed PowerPoints to help us keep our students engaged - and to give us prompts so that we don't have to keep our noses in the binders! If you follow the presentation, you will hit everything in the module.
You will want to have your module close by for reference, but we have taken away any need to use your document camera to project the lessons. This was a massive amount of work - updated September 2014 - and I hope it makes your lessons a little more compelling for your students!
