Teacher conferenced with various groups using learners knowledge as a guide and answered all questions by probing and encouraging learners to communicate their thinking collaboratively so
that they could do critical thinking and show creativity as they learned (4 C’s for today’s Learners)
 
Learning Outcomes

Level 3: Ordering decimals
Level 4: Decimals and place value to 3 places
Level 5: Recurring decimals (extension)
 
Success criteria:
Learners are successful if they can order decimals, read decimals correctly, compare decimals
and write decimals as percentages
SOLO Taxonomy
 
Do Now (Introduction)

Rearrange these letters “a decimal point” to explain what a decimal is. Use each letter only once and use all letters.
Teacher reads the instruction aloud and answers any questions posed by learners
Learners work independently and/or collaboratively as they work towards a possible solution
I’m a dot in place
 
Lesson sequence

Rearrange given letters to better understand what a decimal point is
If I gave you $500 would you be happy?
Now along comes the decimal point and lands just after the number 5 to make $5.00, would you still be happy? Class discussion about the impact of the decimal point on the value of the money
Answer question 1 and 2 to determine learners’ curriculum level
Question 1. Four friends, Mele, Tui, Tevita and Anna can jump 3.1m, 3.15, 3.01 and 3.10m respectively. Arrange these distances in ascending order
Teacher comment: When rearranging or comparing, decimals, look at the first digit, of each number: if they are similar, then look at and compare the next digit eg in 3.15 and 3.01 (1/10 is greater than 0/10 or 15/100 is greater than 1/100), so 3.15 is greater than 3.01
Thinking/discussion: When comparing 3.1 and 3.10 both can be read as having 1/10, so the two decimals are equal.
Any zero after the decimal point that is not followed by another number is just a placeholder
Question 2. Draw a number line (any length) from 0 to 1. Mark the middle and give it a decimal value. Keep finding the middle until you reach 3 decimal places.
Use your learning outcomes table, from Mrs Dunn Maths site to determine the curriculum level for each Question (this is for learners to identify their learning needs)
Teacher provocations
How would you read this decimal 1.25?
one and twenty five hundredths
one and two tenths and five hundredths
one point two five not one point twenty five  Learners work independently and/or collaboratively
Discuss how to read and compare decimals
Explore learning using online resources
Make learning visible by creating personalised notes documenting evidence of learners’ understanding of Decimals
Teacher provides opportunities for learners to develop and demonstrate their thinking by discussing with peers and documenting on a Google doc. Teacher expectation is that of learners’ managing their learning.
Learners selfmanage by choosing the appropriate curriculum levels for the topic and can move on to the next level if they feel confident in their ability
Learners show evidence of their thinking and learning by creating personalised notes after navigating the hyperlinked Decimals resources on Mrs Dunn Maths site
All evidence of thinking/learning is visible on a Google document which is shared with the teacher and can also be shared with peers for commenting
 
Learning Experiences

Learners work independently and/or collaboratively. Writing decimals in words and symbols as learners often confuse decimals with money and read it incorrectly.
Learners work independently and/or collaboratively. Comparing decimals on number lines to see progressions from smallest to biggest
Learners work independently and/or collaboratively. Understanding decimals as percentages eg 0.25 is 25%

Curriculum
Convert common Decimals up to 2 dp) to Fractions (L3) which will lead on to basic operations with fractions (L4,5 )

Daily life
Fractions are used in baking or cooking. Basic operations are used eg if ¼ cup of sugar, sometimes it is necessary to either double or halve the recipe.
 
Reflection

More emphasis needs to be placed on place value, particularly for numbers after the decimal point so that learners use words like tenths, hundredths and thousandths confidently. Using money as an example when learning about decimals is contradictory as $5.70 (five dollars seventy) is not read as five point seven zero dollars. There are no tens, hundreds and thousands after the decimal point; instead it is tenths, hundredths and thousandths

Do Now (Introduction)

On weekends or after school, where do you see Fractions and/or Percent? Online activity
A few volunteers explain what they wrote on the lino board while the rest of the class listens attentively and respectfully
 
Lesson sequence

Question 1. Retailers express some of their discounts as Fractions and others as a Percent. Explain how to determine which discount will benefit you the most?
Briscoes is offering a 25% discount on a $20 fan and The Warehouse is one third discount on a $30 fan.
Which retailer is offering you a better buy and how much change will you get if you pay with a $50 note.
⅓ is bigger than 25% (¼) so Better deal is at The Warehouse
Activity 1
*Screenshot a house on the internet that you would like to buy.
a) How much is the house?
b) Write this amount in words. (Level 3)
c) What will the ⅕ deposit be? (Level 4)
d) How much will still be owing? (Level 3)
Real estate commission in Auckland ranges from 2.95  4% for the first $300 000 and then 2  2.5% thereafter. A base fee up to $500 is charged regardless of whether the house is sold or not. GST is also added.
e)How much commission would be made if you sold your house at the price mentioned in (a) (level 5)

Trip to Wellington
24 students in 9KLe were planning a trip to Wellington in September with the lovely Mr Mansell. The cost of the trip was $80 per student. The group had a sausage sizzle to raise funds. They needed 8 loaves of bread. Elstree Dairy had bread for $2.20 each, but the owner gave them a 15% discount. Students also bought $50 worth of sausages. Onions and tomato sauce were donated by the Geek Cafe. Students sold 110 sausages for $1.50 each and then had a bake sale a few days later. All baked goods were donated and students made a profit of $250. Mrs Dunn offered to donate ⅕ of the amount raised at the bake sale. How much would each student have to pay?
