I can count up to 200 on my own. I can read, write and order numbers from 101 to 200. I can add big numbers that equal more than 100.

LO: Count up to 200. Let’s count up to 200 from 100. Can you do it without the square this time?

LO: Count up to 200. Here’s a chunk taken from a 200 square. Can you help teacher fill in the missing numbers?

LO: To write numbers from 101 to 200. (On whiteboards) Teacher call out numbers between 101-200 for the children to write down. Use the square to check 100-200 Square Call out 2 numbers - children must write the bigger number.

LO: To add numbers that are equal to more than 100 We are going to add some BIG numbers now! We will do it the same way we always have: Down a step to add 10’s Across to the right to add 1’s

LO: To add numbers that are equal to more than 100 Here’s a part of a number square. Let’s try this sum!

LO: To add numbers that are equal to more than 100 Let’s try this sum using this chunk of a number square! 83+34=

LO: To add numbers that are equal to more than 100 Let’s try this sum! 76+12=

LO: To add numbers that are equal to more than 100 Let’s try this sum! 80+40=

LO: To add numbers that are equal to more than 100 Let’s try this sum! 101+15=

LO: Add numbers that equal more than 100 using a 200 square (Use the 200 square in Abacus Workbook 3 page 4 as resource) Green: Yellow: Red: 101+20= 104+30= 106+ 21= 102+ 40= 121+45= 105+ 43= 107+21= 109+ 41= 106+ 8= 120+ 50= 104+ 30= 145+ 52= 101+ 27= 137+ 32= 109+ 55= 150+ 45=

Maths LESSON 4 Adding big numbers

Learning Objectives Success Criteria Count up in 10’s from any number Add 2-digit numbers on a number line by adding 10’s then 1’s. To understand that it is simpler to add a small number to a bigger number. I can count up in 10’s from any number I can add on a number line by adding 10’s first and then 1’s I know to add the smaller number to the bigger number in an addition sum

LO: To count up in 10’s from any number We can all count up in 10’s. But can you count up in 10’s from ANY number? Like….6? 6, 16, 26, 36, 46……..can you keep going? Someone splat a number and we will try to count up in 10’s from that number! http://www.primarygames.co.uk/pg2/splat/splatsq100.html

LO: To use skills to make adding easier. When we are doing an adding sum, it is a good idea to put the BIGGER number first and then add the smaller number! 8+71= Let’s make it easier!! 71+8=

LO: To use skills to make adding easier. Can you help the teacher to re-write these sums to make it easier to add? 12+46= -------> 63+24= -------> 11+89= -------> number line

LO: To use skills to make adding easier. Everyone should have a number line to help them! Change around the sum so you are adding the small number to the bigger number. Mohammed wants to buy a schoolbag for 54 dirham and shoes for 35 dirham. How much money does he need? 54dhs 35dhs

LO: To use skills to make adding easier. Omar wants to buy a bike for 72 dirham and an ice-cream for 11 dirham. How much money does he need? 72dhs 11dhs

LO: Revise subtraction Can you remember how to subtract big numbers? What direction do we take when taking away 10’s? What about taking away 1’s?

LO: Revise subtraction There are 30 falcons sitting on the house. 5 of them fly away. How many falcons are left on the house? Can you write the number sentence that goes with the word problem? Write it in the box!

LO: Revise subtraction Mohammad has 50 dirham. He buys a toy spinney for 38 dirham. How much money does he have left? Take away the 10’s in your head first, then the 1s Show on the number line what your answer is --> Number line tool Draw money to show his change.

LO: Solve word problems with addition and subtraction. 45d 32d 24d I want to buy a spinney and I have 75 dirham. What change will I get back from the shopkeeper? I want lego and a playdough. How much will that cost? Teacher call out similar word problems

LO: To subtract large numbers Green: Yellow: Red: 40-20= 65- 21= 66-45= 28-17= 89-72= 45-41= 88-57= 12-12= 89-42= 90-45 77-71= 87-34= 89-52= 65-43= 25-23= 57-35= 100-56=
