Cute numbers is a new concept for me. As I googled the term, I discovered that 4 and 10 are cute numbers. The use of diagram help me to understand the concept better.
There is a large square divided into 4 quarters. Two of these quarters are subdivided into eight smaller squares. These 8 smaller squares together with the last two bigger quadrants make up 10 squares.
Richard Skemp (1978)'s theory on the continuum from relational understanding to instrumental is also new to me. Children need to understand concepts, conventions and procedures.
