Maths - Algebraic Parts

LI: To evaluate the information given to solve an algebraic equations.

For maths, we learnt how to determine the answers to an algebraic equation using information and significant data by evaluating and understanding text.

The first question was 'what is the lowest amount of money that Nana and Grandad would spend to get the Smith family into the movies?'. I solved this because I knew that there were three kids (one was two, one was six and one was eight) and their were two parents. I know that children from 4-16 cost $13 and children under three are free. Parents are $16 so (13x2) + (16x2) = $58, so they would spend a minimum of $58 dollars.

The next question was 'The Smith family bought 3 tubs of large popcorn, 2 soft drinks and 5 ice creams. How much did they recieve from their $25?'. I know that 1 large popcorn is $2, so 2x3=$6. I also know that 1 soft drink is $2.50, so 2.5x2=$5. Finally, I know that 1 ice cream is $2, so 2x5=$10. Altogether they spent $21 and recieved $4 change.

The third equation was 'Mum and Dad decide to buy Christmas gifts for the children’s three cousins, as the movie shop (merchandise) has a sale on. They have budgeted $20 for buying these gifts. What combination of gifts should they buy to stay within the budget?'. They can buy a child’s toy and 2 sheets of stickers, a colouring book and 2 character felt pens and a comic book because that costs $15 altogether.

The fourth question was 'Max’s friend John is invited to join the family at the movies. He is eight years old. He has saved $20 for his movie ticket and treats. Which of the following options is within his budget?'. John could buy a childs movie ticket, medium popcorn, soft drink and a child's toy because that equals $20 altogether.

The final equation was 'The ‘five tickets family price’ would allow Nana and Grandad to pay for the four movie tickets they need to buy, and purchase an additional ticket for John. With this option John would save money on the price of his ticket. How much will John need to give Nana and Grandad for his movie ticket, and how much will he save compared to buying and individual ticket?'. John could give $12 and save $1 because the childrens ticket price is $13 dollars and John is paying a little less.

I found this activtiy very fun because I used my algebraic knowledge to use important information and convert that data to help me solve an equation.
