Ketura- Maths Enlargement

Today we had to enlarge a picture that we had chosen, to draw on the asphalt outside. First, I had to draw my grid on a paper, to see what it would like on the ground. The next day, we all had to go outside to measure and draw our grid. My grid was a 7 by 9 grid. The picture that I had to enlarge outside on the asphalt was an elephant.

To draw my picture using my grid, I had to count the squares while drawing my elephant accurately. I worked out my scale factor which was: 1cm represented 30cm. Enlarging a picture on the asphalt was difficult because some of the things that I drew were in the wrong place.

Tane- Enlargement

Yesterday we were learning about enlargement. Our task today for maths was to enlarge a picture of an ant, hat, dinosaur, or lion. As you can see I tried to enlarge a picture of an ant it sorta came as I pictured it but I drew the last part of the ant to big. The little picture of the ant is 9 centimeters and the large picture of the ant is 18 centimeters so the scale factor is 2. I had to count each square on each picture as I started to draw the larger ant so the measurements could be as precise as possibly. I found this drawing activity a bit difficult because the legs and the circle at the end was hard to get in the exact spots. After doing this activity I would like to learn more about co - ordinates.
