Trying to overcome the counting up in 10's in those first couple of gloss q's...
Might be worth trying to build up some 10x facts - 5x10 and 10x10 and then getting them to use them to solve a problem.
So for the last q would be good to see:
10x10 = 100
10x10 = 100
5x10 = 50 (or jump straight to 6x10)
+ 1 more 10
= 26 tens.
