Measuring Perimeter

In our Measurement unit, we are calculating perimeter by measuring the sides of shapes and finding the total. Perimeter is the distance around a closed shape.

Weekend Math Challenge

If the perimeter of the following shape is 24cm, what is the length of the missing sides? (Hint: The two sides are the same length) Be sure to show all your work and explain your thinking. Your solutions are due to Ms. Earl on Monday.

Math Supplies

All students need to have a 30cm ruler (marked with millimetres) and a calculator. We do not have enough of these supplies at school (especially calculators). Please write your child's name on each item.

Valentine's Math Challenge

Roman has asked his mother to give him some money to buy 
Valentine's Day cards for his class party.  His mother gives him 
$6.00 to buy the cards.  When Roman visits the store he finds that
there are 5 cards in each box.  One box costs $1.40.  Roman has 26
children in his class, but he doesn't need a card for himself. He does want to give Ms. Earl a valentine. (Don't worry about the tax) 

a. How many boxes does Roman need to buy to have 26 cards in all?

b. How much money will Roman spend if he gets enough cards 
     for the class?
     
c. Will Roman have enough money?  How much money does Roman have left over, or how much more money does he need?
