Extend powers term 4 maths

WALT:Extend powers to include integers and fractions.

I found the assessment task hard but easy.And I learnt a lot about exponents.

Assessment task

maths

Assessment Task: relate tables, graphs, and equations to linear and simple quadratic relationships found in number and spatial patterns.

WALT: relate tables, graphs, and equations to linear and simple quadratic relationships found in number and spatial patterns.

Assessment Task: A car rental business has two rental schemes, red and blue for rentals up to ten days. These schemes are advertised in their brochures with this graph.

Use the following information to work out how many days of rental would carry

the same total cost on either the blue or the red scheme (show your working).

• The area under the graph gives the total cost of renting.
• The schemes each follow a linear pattern, cutting the vertical axis at 120 and 170.
• Both blue and red schemes cost $110 on the 4th day of rental.

Maths term 1 statistics investigation

WALT:Plan and conduct surveys and experience using the statistical enquiry cycle.

For the last couple of weeks Ryan and I have been working on gathering peoples opinions on where they like to sit, so we can make a graph with the information.In this screen shot you can see the graph of the results and the percentage of who likes which zone.The percentage of people that voted for other was 29.4% and whanau zone had the least percentage which is 7.4%.

Our SOLO level achieved was Extended-Abstract because I think we collected data efficiently.

Our next step is to conduct a higher level investigation.

Apply standard form

WALT:

Apply standard form, significant figures, rounding, and decimal place value.

For the last couple of I have been focusing on this walt and I have been able to 

finally blog about this e.g 41 standard form is 4.1 small 1 . 

My next step is statistics.
