The Scribe for today- April 3rd 2006!!!

Today in math, first thing we did was mental math.

April 03 2006 Mental Math
6x3= 18
Three dollars equal 300 pennies.
3-5x6= 27
0, 5, 10, 15, 20, ___, ___, ___. answer: 25, 30, 35
0x1,234= 1,234
3/ 27= 9
The product of two and three is ______. answer: 6
The sum of six and eleven is ______. answer: 17

Then we learned about how to find the find the perimeter of an object.

The rule for finding the perimeter: Add all the sides together.

Finding the perimeter of an object
(To find the solution, read the RULE above^)

answer: 8+15+8+15= 46

Find the perimeter of these objects:

18+18+18+18= 72m
18x4= 72m

42+9+42+9= 102cm


Finding the missing measurement

30+8+8=46 76-46=30
The missing measurement is 30mm
How did you get 30mm?
76- total perimeter
Subtract the total to 46

?= 30mm

Total perimeter- 42
?= 12

Determing Perimeter

What is the perimeter?
answer: 10+10+10+10= 40cm

answer: 25+25+40= 90

answer: 20+10+12+9+5=56

Later on today...we had to create a shape for each given perimeter

A.) 28cm B.)11cm C.)33cm D.) 20cm

a.) 7+7+7+7=28cm
b.) 2+5+4=11

12+10+11= 33cm
d.) 5+5+5+5=20cm

Four people went up to the board and drew a diagram for each given perimeter (a,b,c and d). Each person had different styles to other people.Some were even creative than the other.

Eight minutes before class was over, Mr. Reece asked a question about a square.
Is a square a rectangle?
We had a little survey. Two people said yes and 2 people said no. Then Mr. Reece had to break the tie, so he asked one more person. That person said yes!
Is it yes or no?
Answer: YES! A square is a rectangle because the opposite sides are equal. It may not have the same size but the sides are all equal.

Create a shape for each given perimeter:
a.) 28cm b.)11cm c.)33cm d.) 20cm

You can only draw a shape in minimum of 5 sides!

The next scribe will be...
