Predict: I will need to work out the value of each different bead.
Clarify: I will then need to add the beads to confirm my answer.
Find the big question: what is the value of the last string?
Solve: I thought of some number combinations that add together to equal 16. I worked out that the dark shaded beads equal 2 and the light shaded beads equal 5 then I worked out those for my answer then I worked out the blank beads for 6 so then the answer was 23.
Summary: I used the guess check and improve strategy.
