Hello Irmi! First, I want to say welcome and I will also be teaching MFW1st and MFWK this year to my two children!
MFW1st grade has math incorporated into the curriculum. The basic package comes with addition and subtraction practice charts. There are also two other items in the deluxe package (but if you are not purchasing the whole deluxe version you can buy them individually.) One of these items for 1st grade is called "The Complete Book of Math". It's colorful and it has some games and activities in it, not just worksheets. From what I understand, it is scheduled into the MFW1 TM now (I think that's new and it might not be in older editions of the TM). The other item is the Animal patterns book and the wooden pattern blocks. Both look fun to me and I think we are going to try these out, too.
For both MFWK and MFW1 there is also math every day with looking at the calendar and the 100 chart. In K there are also measuring activities, making charts, counting coins, lots of informal math activities.
Two other items that we used last year and will continue to get out this year are from the preschool 3-4 yr old package. They are the "number puzzle boards and pegs" and the pegboard. We used them a lot for lots of different math activities last year and both my PreK'er and my K'er loved them.
Just some other ideas to consider for children that are the same age as mine. ;)
