Making An Algorithm - 1

Sam and his Mom walk to school. What is the first step in the algorithm?

• Walk down the street

• Leave the house

• Arrive at school

• Cross the road

Sam says, 'If it is wet I put up my hood. I talk to my Mum. We walk down our street. Mom laughs at my jokes.' What is the next step in the algorithm for getting to school?

• See if it is raining

• Tell jokes

• Walk down the street

• Tell funny jokes

Sam says, 'At the end of our street we turn left into Lincoln Road. Lincoln Road is very long. It goes all the way into the town center. That’s where the shops are.' What is the next step in the algorithm for getting to school?

• See how long Lincoln Road is

• Go all the way to the town center

• Go to the shops

• Turn left at the end of the street

Sam says, 'We pass the Methodist church on our left. Then we cross the road at the crosswalk.' What is the next step in the algorithm?

• Go as far as the crosswalk and cross the road

• Go into the Methodist church

• Go as far as the Methodist church

• Turn left into the Methodist church

Sam says, 'After the crosswalk, we carry on walking along Lincoln Road. Some days my friend Luke and his Mom catch up with us.' Which one of these will you write down next in your algorithm?

• Keep walking along the same road

• Meet Luke and his Mum

• Meet Luke

• Meet Luke’s Mum

Sam and his Mom then get to the highway. They cross the road. Sam presses the button and waits for the green man to light up before they cross the road. What is the next step in the algorithm?

• Walk along the highway

• Go back home

• Cross the highway

• Turn back at the highway

Sam says, 'We get to the corner of Lincoln Road and Chester Grove. We turn right into Chester Grove. There is a shop on the corner. It sells candies and drinks. On Fridays, Mom lets me buy some candies at the shop.' What will you write down next?

• Go into the shop on Mondays

• Buy some candies

• See how many candies you get

• Go to the corner with Chester Grove and turn right

The school is further along Chester Grove. It is on the right. What is the next step in the algorithm?

• Walk along Chester Grove as far as the school

• Go to the classroom

• Turn right into school

• Walk into school

The school is on Chester Grove. It is on the right. Sam and his Mom have reached the school gates. What now is the next step in the algorithm?

• Turn left into the school

• Turn right into the school

• Go to the classroom

• Go back home

What is the final step in this algorithm?

• Cross the road

• Walk along the street

• Go back home

• Go through the doors into the school
