In Pre-Algebra we used this website to make shapes and find their missing angles.In this shape we made a triangle,and had to find its missing angle but it only gave us the measurement of two angles. By knowing that there are one-hundred and eighty degrees in a triangle we added the known measurements of two angles we subtracted one-hundred and eighty degrees by the sum of the two known angle measurements and that gives us the missing angle measurement.
There is no picture for this but in math we used regular playing cards with positive numbers and negative numbers.First we got regular playing cards ,the red were negative and the black were positive numbers.Also our teacher told us if we were only multiplying,dividing,adding,and subtracting for this round and then you and your partner across from you each put down three cards and flip them all over.Then you multiply,divide,add,or subtract on which one our teacher said(i.e.)(if using multiplication for this round and numbers are red 6,black 3,and red 9,the problem is -6 X 3 X-9 then you solve the problem and the biggest number wins.
For this next project we measured our height in centimeters,but sadly there's no picture.Everyone in our class (about 40 people) lined up to use on of the six meter sticks in the class room to measure their height in centimeters.After finding all of our heights we put them on a chart and graphed them from least to greatest.Then we found the mean,then average,median,the on in the middle,mode the one that shows up the most,and range,subtracting the least from the greatest.
In this project for math we made tinfoil boats.We paired up with another person in the class and made a boat design and made a boat that would hold the most pennies in water.First we found the length,width,and height,and used those to find the area and estimated volume.Then we tested our boat and put pennies in it.The only hard part was not crinkling the foil and making air holes for water to leak through,and placing the weight of the pennies evenly so the boat doesn't lose balance and capsize.Then the next day we made changes in our design and did the same thing found length,width,and height,and found area and estimated volume, then tested it again to see if we could get our new boat to hold more pennies than the first boat.
