This is Unit 3 (Adding) which includes 14 days of lessons. If you are using the Singapore Math program you know that there is a lot of prep work involved prior to teaching each lesson. I have created this smartnotebook file to make my life and hopefully yours a little easier. Each lesson has the activity you need to introduce the topic. There are 35 slides and two of the interactive games are included in this unit. I used the teacher edition scripts and created all the activities so that all you have to do is have the teacher manual and this smart file and you and your students will be all set.
