well, we've not started yet. but each lesson is a front and back worksheet. that's it. lesson 1 for example is basic K review. the front of the worksheet is writing the number "0", & the back of the worksheet has dominoes - but the child need only write "0" where the domino represents zero.
The teacher guide has several ideas for each lesson. For ex. lesson 1: You start off counting 1-20 with a visual aid...showing the students each number as you count aloud. Then you all practice writing zero in the air. Then show your children a brown paper bag. Ask them what is in it? nothing. Hold the bag upside down and shake it. Again, explain that nothing is in the bag. Zero means nothing. Nothing at all. You can have a flannel board with a duck pond & ducks (which I'll just use our lucky ducks game) and show that no ducks are swimming. Zero means nothing. Then do the 2 workksheets. Lesson is done.
The review stuff is easy for sure, but the curriculum is very thorough imo and does not stay like that. By lesson 6 you're doing less than & greater than...then lots of addition....by lesson 60 - you're doing money...then you move into time....fractions....subtraction...etc. there are 2 student workbooks with 170 lessons total (2 pages per lesson). i think i paid $35 with shipping for the student books, teacher book, and speed drills book. if you have specific questions, i'd be happy to answer them. hth!
