I’ve been working to update several of our math courses. Some other courses are getting updates, but levels 1, 2, and 3 are getting whole new courses. We typically switch in new courses around the 4th of July. By then most people are finished their school year but not starting the new year yet.
The old courses will be available for you to finish if you will find yourselves in the middle of one of those courses when summer rolls around. You should just finish out the course you are in.
The change will mostly just affect those in Level 1 Math currently. The other levels are not really introducing new content. Things are just moved around to get in some more practice with multidigit addition and subtraction in Level 2 and multiplication and division facts practice in Level 3. The only real content change takes place in Level 1 Math. In the new course, they work on all their math facts up to 9 plus 9 and 18 minus 9. That means in the new Level 2 Math they will be expected to know those.
The current online course and offline parent guide both make mention of that and ask you to practice those facts over your summer break.
We will plan on releasing all the new books to match these new courses in April. In April we will also release all the updates to the other books.
