# Year 7: week 2 (number knowledge and measurement)

This week we focus on multiplication and division basic facts, and working with length and area.

### Day 1

Number facts

• Go to the number facts pathway in e-ako maths.
• Choose the multiplication and division learning tool.
• Click “Check all facts” and answer the questions. The green ticks show the facts you know.

Measurement e-ako

• Go to the measurement pathway in e-ako maths.
• Choose e-ako M3.7 (the seventh yellow button on the third row).
• Work through pages 1-7 which are about measuring lengths.
• Write down all the units of length you know of. How are these units connected? For example, how many centimetres are in a metre?

Measurement activity

• Go to the activity Bouncing Back. Complete only Activity One. You may need to look online to find out how to draw a scatterplot. Software like Excel and CODAP can help.
• If you drop a ball from twice as high, does it bounce twice as high? Why does that happen? Explain your ideas to a family member.

### Day 2

Number facts

• If you have facts to learn go back to the multiplication and division learning tool.
• Click “Learn a new fact” and complete the mini lesson. Do this three times.
• Click “Check recent facts” and answer the questions.
• Return to the number facts pathway and play the “Number Facts” game “All Numbers” a few times.
• If you have no facts to learnplay the game Calculator Golf. You will need a calculator.

Measurement e-ako

• Go back to e-ako M3.7 on the measurement pathway in e-ako maths.
• Work through pages 8-13 which are about measuring the area of a Marae.
• If you know the side lengths of a rectangle, in metres, how do you calculate the area? Explain your method to a family member.

Measurement activity

• Go to the activity Can You? Note that the population of New Zealand is now about 4 700 000 people.
• Does your household use 750 cans per year? If not, why do you think the number is so high? Explain your answer to a family member.

### Day 3

Number facts

• If you have facts to learn go back to the multiplication and division learning tool.
• Click “Learn a new fact” and complete the mini lesson. Do this three times.
• Click “Check recent facts” and answer the questions.
• Return to the number facts pathway and play the “Number Facts” game “All Numbers” a few times.
• If you have no facts to learnplay the game Matrix. Instead of changing a dice with stickers you can use a set of playing cards with the numbers 4, 5, 6, 7, 8 and 9.

Measurement e-ako

• Go back to e-ako M3.7 on the measurement pathway in e-ako maths.
