Mon Oct 31st – Algebra – Expanding Brackets

LEARNING OBJECTIVE: Discover how to remove the brackets from an algebraic expression by expanding.

SUCCESS CRITERIA: You will be able to expand an expression accurately

KEYWORDS: EXPRESSION, EXPAND, BRACKET, SIMPLIFY

STARTER:

1. Find the value of 4b + 3 when i) b = 2.5, ii) b = -1.5, iii) b = ½
   
2. Find the value of 12 / y when i) y = 2, ii) y = 4, iiI0 y = -6
   

Where A = a² + b² , find A when: i) a = 2 and b = 3, ii) a = 5 and b = 7, iii) b = -1 and c = -4

LESSON: Work through This MyMthas Lesson.

Mon Oct 10th – Building a Cumulative Frequency Table and then Drawing the Cumulative Frequency Curve on a Graph

LEARNING OBJECTIVE: How to Add a cumulative Frequency Column to a Frequency Table and then draw the Cumulative Frequency Graph

SUCCESS CRITERIA: You will be able to add a cumulative Frequency Column to a frequency table and then draw the resulting Cumulative Frequency Curve.

STARTER: Use Screen 1 from this MyMthas Lesson

Cumulative Frequency Videos

LESSON: Use screens 2 – 4 to recap cumulative Frequency Curves and finding the median from the cumulative frequency.

Move on to This Mymaths Lesson to look at Cumulative Frequency From Grouped Data

Lots of Practice from this Worksheet. For each Table wirte down the Median value from your graph

PLENARY: Checking answers on MyMthas Screens, going around tables to check answers from Worksheet

Mon 3rd October – Mean from a grouped frequency Table

LEARNING OBJECTIVE: Apply the method to find the mean from grouped table of data

SUCCESS CRITERIA: You will be able to find the mean from a grouped frequency table

STARTER: Put screen 6 on IWB from this MyMthas Lesson (discrete data) and ask students to work out the mean

Work through answer with them after giving them some time to complete it.

IF ANY Issues use next screen for a further example.

LESSON: Work through the first screen of this Mymaths lesson to show how to find the mean from a grouped frequency table of continous data. Hand out grids in order to complete the mean for teh boys data

PLENARY: Use MyMthas screen to check data.

Let them work through next example on sheet 'Nicole's Cucumbers'. Check answers.

Repeat Nicole's Cucumbers on IWB as MyMaths generates a new example every view.
