Kilometers per day for 10 mile day:

1. Look at the chart that compares measurements. Notice that 1 mile is equivalent to 1.61 kilometers. 

2. What do you know about decimal places and place value? What relationship does 1 have with 10? 

3. Try multiplying the number of miles by 1.61 kilometers. 

Last four ties:

1. Find the total width in feet and inches before trying to convert it to metric. 

2. Try calculating the width of the ties first, and then the width of the spaces between them. Add them together. 

3. Round to the nearest foot, then convert to meters. 

4. How many meters are in 1 foot? How many will be in the answer you got for number 2 part 1? Is this number greater or less than the amount in one foot? What operation can you use to get the larger number (multiplication or division?)

Weight of the ties:

1. What do you know about multiplication? Do you have groups or a certain number of objects?

2. Try repeated addition. Then see if you can check your work with multiplication. 

3. How many pounds are in 1 kilogram? How many will be in the answer for number 3 part 1? Is this number greater or less than the amount in one pound? What operation can you use to get the larger number (multiplication or division?)

3. How many pounds are in 1 kilogram? How many will be in the answer you got for number 4 part 1? Is this number greater or less than the amount in one pound? What operation can you use to get the larger number (multiplication or division?)

Infographic/Poster: The purpose of an infographic is for people to see and understand information quickly.

1. What visual elements can you include that are easy to understand?

2. Use moderate colors, not too bright. Pick 2 or 3 and stick to those.

3. Try drawing your idea out on a piece of paper before actually creating it. This way you can plan enough space for words and pictures.
