Warm-up, learn, try it together, practice, then a quick check. About 15 minutes.

What children learn in Level 35

Omar has 23 red beads and 35 blue beads. How many beads in all? In all means put the parts together.
23 plus 35 is 58. Omar has 58 beads in all!
Zoe has 52 shells. Kai has 37. How many more does Zoe have? Line up the bars and look at the difference.
Count up from 37 to 52: 3 to 40, then 12 more. That's 15. Zoe has 15 more shells. That also means Kai has 15 fewer!
Ben has 18 cards. Nia has 9 more than Ben. Nia has the same as Ben, plus 9 more: 27!
