Plan of work

FIRST WEEK

The stem.
Read pages 4 to 11.

· You must look at each stem.
For example, on page 7 it says: "Let us look at a yam plant."
Go to the field, and look at the stem of a yam.
If there are no yams in your village, look carefully at the drawing.

· You must take good note of how one stem differs from another or is like another.
Make sure you understand what the stem does.

SECOND WEEK

The buds. How a leaf is made.

Read pages 12 to 18.

· To help your memory, read again pages 4 to 11.
· Look carefully at buds.
· Take a good look at the leaves you have picked. Look carefully, you will see the veins.
· Learn the new words, such as vein, midrib, leaf- stalk.

THIRD WEEK

What the leaves do.

Read pages 19 to 23.

· Read again pages 12 to 18.
