part 4

37 Now I am making a cut at this angle in this bit of wood. The blade is going through the wood. This is my knife. This is the blade of my knife. l am making a line on the wood. I am making a line with a pencil. This is the pencil. This is the line.

38 "Keep on the line when you are cutting. Don't go off it." Oh! You are going off the line! The cut is not on the line. That is bad! The cut is off the line. You did that! You gave a push to the table.

39 No, I did not! Your knife went off the line. Yes. It went off the line. Do it again! It's not very bad. Here is the line. And here is the cut. a straight line a bent line Tom is making another attempt. That is better. The cut is straight. The blade of the knife went straight. Good!

40 Now I have these two bits of wood. I will put them together like this. There is the roof of the house. Now I will put the two parts of the roof together with nails. These are nails. I will make a hole through this part of the roof into the other part of the roof.

41 Tom is making the holes for the nails. Now he is putting the nails in with his hammer. Now the two parts of the roof are together. These are the nails. The roof is ready. Is it strong? Oh yes, it is very strong.

42 Don't do that! Oh, now it is broken! But you said, "It is very strong!" It wasn't strong. I will make it stronger. Give the roof to me, please. I'm giving it to you. Is this line long? This line is longer. Is this bit of wood strong? This bit of wood is stronger.
