Classification word problems

Classification word problems span from lesson 107 to lesson 121.

Classification word problems differ from comparison or sequence problems because classification number families have three names not two. The names for classification number families always refer to a class and two subsets of that class.

If students have trouble identifying the name for the big number, show them how to test the names. Say each name and ask if it tells about the other two names.

The process is:

The teacher says, ‘The names for A are old men, men, young men. Which name tells about all?’ and signals (auditory).
The teacher asks, ‘What’s the name for the big number?’ and signals (auditory). The teacher continues same process with other two problems.
The teacher says, ‘Make the number family for A. Use the underlined words. They are old, men, young,’ and observes students and gives feedback.
The teacher says, ‘Check your work for family A. What are the names for the small numbers?’ and signals (auditory).
The teacher asks, ‘What’s the name for the big number?’ and signals (auditory).
