Lenses

A lens is a custom view of the content in the repository. You can think of it as a fancy kind of list that will let you see content through the eyes of organizations and people you trust.

What is in a lens?

Lens makers point to materials (modules and collections), creating a guide that includes their own comments and descriptive tags about the content.

Who can create a lens?

Any individual member, a community, or a respected organization.

Educator’s page

One more

Teacher will assess whether learners understand the concept of 1 more by doing the following on the mat:

☻ Put out 4 counters. Make it 1 more (different colour). How many?

☻ Do the same with 7, 3, 9, etc.

☻ How many children are there in the room? We get 1 more - how many are there now?

Let 4 or 5 learners stand in front. How many children are there?

One more?

☻ Now observe and assess as similar steps are done making ONE LESS.

Problem Solving

☻ Learners need to be confronted with problem solving many times so that they are able to work out their own strategies.

☻ Take for example the problem at the bottom of page 15.

☻ Set a similar problem and observe how the learners attempt to solve it.

☻ Discuss their different strategies.

☻ They may use counters or draw pictures or do it mentally, etc.

☻ They must be able to explain their strategies in words.

☻ Discuss different strategies.
