Order of Operations - Rich Task

Today for Maths we were focusing on BEDMAS (also known a BODMAS) which stand for Bracets, Exponents, Division, Multiplication, Addition, and Subtraction. This session I worked collaboratively with Jeremiah and Fraidoon. For this task we were to solve 8 BEDMAS questions then choose three to to make a DLO about. This was pretty easy since I've already done this in my previous school. We have chosen questions that require us to abide by the BEDMAS rules. On our DLO there is a answer sheet that will give you the answers to other questions. We also wrote an explanation explaining how we got our answers. 

Classroom Age - Fractions

 

 This week one of our set tasks challenged our fraction knowledge. The question was 'in the classroom, ⅔ of the children are ten years old. ½ of the remaining third are nine years old. Four children are 11 years old. How many children are there in the classroom altogether?' For this particular question Jeremiah and I had to firstly figure out the amount of students in the whole class. The answer to that part of the question is 24. If their were four eleven year old's and that is 1/2 of 1/3, that means that their are also four nine year old's. Lastly we subtracted eight from 24 then the rest of the children are ten years old. At the end we figured out that their were, four eleven year old children, four nine year old children, and 16 ten year old children

Angles Maths Problem

Today maths was exciting because we were finding the interior angles of triangles to 180 degrees. We were given a paper sheet with shapes that had missing angles. I learnt that the rule for finding angles is the interior angles of a triangle all add up to the same value 180 degrees. At the end we were to make a DLO with one of the shapes to discuss about.
