Children you may like to:
- complete the silhouettes of two of the convex shapes that can
be made;
- find out what you can about the terms convex and concave.
Find ways of explaining the ideas to your friend,
family and teacher.
- make a collection of things that are concave or convex or
both;
- invent an acrostic for both CONCAVE and for CONVEX (hint: Xray/
Xylophone/ Xmas..).
Parents you may like to:
- explain your understanding of the terms convex and concave and
how you remember which is which;
- form a collection of things from around the house that are
convex/ concave in design; e.g. a empty cup - is this convex or
concave or both? what about a full cup?
- explore what happens when looking in convex/ concave
mirrors
- find other words that are often used to mean convex/ concave
Can you find a 7 letter word for convex? 8 letter word for concave?
etc..
Teachers you may like to:
- investigate the other 11 REMAINING convex figures that can be
made using the tangram
- explore when convex/ concave lens and mirrors are used and
why.
- explore more fully the mathematical definitions for convex and
concave shapes (see below)
- consider where terms like 'rude health' come from and try to
list more that are similar
- discuss in what other contexts animals are used to describe
behaviour and other human characteristics? e.g. (Mai Ling) being
badgered by the workmen horsing around! wolfing food
down!......
