Wow so many things I've never heard of before. Thank you so much for your suggestions and taking the time to answer. I never would have thought of such things like a scale or balance before but it makes perfect sense.

I have bought a base ten number concepts set and fractions set and that's it. I've seen c. rods being recommended. Is there anything else?

Hilarious!

Was the HIG helpful? I was thinking of just buying the textbook and activity book.

Can anyone recommend a good toy clock or cash register to practice and play?
