Sequence word problems with abbreviated skip box

Sequence word problems with

abbreviated skip box

In lesson thirty-three students work problems sets that contain both comparison problems and start-end problems.

The structure provided by the teacher is reduced progressively until students work problems with little guidance.

The process is:

• The teacher says, ‘Read problem B’ and calls on a student. The teacher says, ‘will you write the letters E and S in family B?’ and signals (auditory).
• The teacher says, ‘Raise your hand when you know if E is the big number or a small number for the grapes’ and scans the students. ‘Is E the big or small number?’ and signals (auditory).
• The teacher says, ‘What’s the first small number in family B?’ and signals (auditory).

The problem students usually have is that they are not sure about whether to write S and E in the family or to write letters for two things that are compared.

The simplest correction is to tell students to find the sentence that tells them how to make the number family. If the sentence compares two things, or tells about two things, the family needs letters for those two things. If it does not then the family needs the letters S and E.
