I think the lesson "Making 5" should be before the lesson "Making 10".

My suggestion:

-- Mix the two topics "Making 10" and "Making small numbers" in a single topic called "Making numbers within 10";

-- Then order the video lessons by (1) Making 5, (2) Getting to 10 by filling boxes and (3) Adding to 10;

-- Then order the exercises by (1) Making 5, (2) Make 10 (grids and number bonds), (3) Make 10 and (4) Making small numbers in different ways.

In that way, I guess, the content will be more intuitive and organized.
