WALT: solve addition & subtraction problems using a range of strategies

• Squares:Review addition of simple 1 digit problems. Ensure all students at least count on from the largest number.
• 4+5 =
• 8+6 =
• WALT: solve add/sub problems by splitting numbers to make tens
• Show students Q1
• Direct students to solve it then share working. Use this as a review of progression.
• Show students Q2 & Q3
• Direct students to solve independently. Provide students with blocks and number lines if needed.
• Discuss as a group ideas and strategies.
• Show students Q4
• Direct students to solve it then share working. Use this as a review of progression for subtraction.
• Continue with Q5 if learning is need for subtraction by splitting to go back through tens.

Lesson Name: Week 3 & 4 - Fractions Reflection

Teacher Notes:

Warm Up: Adding by splitting (6+4, 19+3) Adding tens (20+30, 50+20)

WALT: add simple fractions

• Fraction Bits & Parts
• Zookeepers:
• Provide students with a paper with circles for a number of animals
• Tell students how much each animal gets fed. ( ½, ⅓ or ¼ )
• Direct students to cut the food out and “feed” each animal.
• Once students have correctly “fed” each animal directs students to add how much food they needed by making wholes.
• Repeat process by increasing the animals and changing the fraction of what each animal is fed
• Key points
• Fractions must be equal parts of a whole.
• The denominator tells us how many equal parts a whole is split into.
• Like fractions can be added together to make a whole.
• WALT: find fractions of a set
• Farmers
• Give students a paper with a field divided into two.
• Give students 10 animals each and direct students that the farmer wants to put one-half of the animals in one paddock and one-half in the other.
• How many animals do you think will be in each paddock?

Lesson Name: Week 3, 4 & 5 - Fractions Reflection

Teacher Notes:

• WALT: find fractions of a set
• Farmers (Materials)
• After students have shared animals out ask “could we work it out without sharing them out?”
• Prompt doubles ( 5 + 5 = 10)
• Next Problem: 12 animals / four paddocks
• Imaging
• “On this farm there are nine animals and three paddocks, how many will be in each paddock?”
• Put one animal in each paddock. Ask how many are in and how many still need to be put in.
• Record problem as ⅓ of 9 = 3
• Next Problem: 20 animals / five paddocks (1 fifth in each paddock)
• Next Problem: 8 animals / four paddocks (1quarter in each paddock)
• Word Problems
• 40 animals / 10 Paddocks
• Prompt thinking: 1 in each paddock is 10, two is 20, 3 is 30, four is 40.
• or: If you put two animals in each paddock, that would be 10 and 10. That’s 20 so four in each will give 40.
• Other problems
• 100 animals / two paddocks
• 35 animals / five paddocks�
• Find fractions of a length
