A lovely introduction to numbers and math.
This book is currently digital only. I’ll be updating the file to include the last sections (currently it only features up to 3 digits) and then releasing the print version. Any purchases of this file will have their available download updated to the new file when it’s released.
A wonderful introduction to numbers and math, starting with simple, real-world sums, then gradually building, with plenty of repetition to build a strong foundation.
