Place value LG: To Recognise, model, represent and order numbers to at least SC:I CAN READ AND WRITE NUMBERS TO 10,000 I CAN ORDER NUMBERS UP TO 10,000 I CAN COMPARE NUMBERS UP TO 10,000 I CAN PARTITION AND RENAME NUMBERS UP TO 10,000

LG: To instantly recognise groups of numbers to help solve addition problems.
Subitising Subitising is being able to recognise numbers or objects in a small group without counting them! Example: I know there are five coins here just by looking. I did not need to count them!
3
Activity Watch the below video and see if you can identify the number of objects without counting them! –

Subitising a)Look for 3 secs. Close your eyes. b) Say what you saw.

Subitising Write how this makes you feel into your maths book.

Activity: Subitising Practice
With a partner use the subitising cards to practice identifying groups of numbers without counting. 2. Take turns to hold up two subitising cards and add them together without counting all the dots.

*CLINIC* LG: To read and write numbers up to 10,000
1) With a partner, take turns to roll a 9 sided dice. Use place value language to say and write numbers up to a 5 digit number Draw a table like this in your maths books to record your numbers
11
LG: To order numbers up to 10,000
3) Draw a place value chart into your math books. Write the numbers into the chart from smallest to largest 4) Use M.A.B to help you if need. •1, •1, •4, , 267 •47, •86, , 780
12
*Clinic* LG: To order numbers up to 10 000 ON A NUMBER LINE
5) Plot these numbers on a number line from smallest to largest Think about the smallest and biggest number that you need on your number line! •303 •5,183 •1,604 •1,038 •23, 485 •23, 675
13
*Clinic* LG: To compare numbers up to 10000
8) Create a number statement using “less than” or “more than” to describe the difference between two numbers. On the next slide calculate the difference between the two numbers and include this in your statement. E.g 4,422 is 200 less than 4,222
14
*Clinic* LG: To compare numbers up to 10000
Compare the below numbers: A B C D E F Make three different sets of numbers to make your own comparison about 9) Justify your answer for each number. How do you know it is bigger/smaller?
15
LG: To rename numbers using MAB BLOCKS
Make the below numbers 2 different ways using MAB blocks. Take a photo and upload it onto Seesaw. ,548 1, ,119 4, ,234 6, ,765
16
LG: To count backwards and forwards in place value parts
10) Complete the table below. The first two are done for you.
17
*Clinic* LG: To use expanders to partition and rename numbers
We can use expanders to help show us the value of each digit in a number. When we use expanders we are looking at writing each digit in full. This is called expanded notation 11) Use the template to cut out and create your own expander!
18
LG: To use expanders to partition and rename numbers
12) Use your expander two write your number in ones, tens, hundreds and thousands
19
Lg: To use your number expander to rename numbers
1) Make each number below with MAB blocks 2) Use your expander to rename the below numbers in 3 different ways. For example 4,236 is the same as: 4 thousands and 236 ones 42 hundreds and 36 ones 423 tens and 6 ones 125 567 102 3,456 6,782
20
*Clinic* LG: To partition and rename numbers
12) Use a number expander to complete this table: Number Partition Number in Ones Number in Tens Number in Hundreds Number in Thousands 3 456 (example) 3456 Ones 345 Tens and 6 Ones 34 Hundreds and 5 tens and 6 ones 3 Thousands 456 ones 567 1 812 81 467
21
What number am i? 3 thousands and 20 tens 7 thousands and 10 hundreds
5 thousands and 14 units 28 thousands and 14 hundreds 352 hundreds and 30 tens
22
*Clinic* LG: To use the split strategy to add two numbers
Use this method to solve the below problems (the ones in red you will need to TRADE). 2, , 223 3, , 329
23
*Clinic* LG: To use the split strategy to subtract two numbers
Leave the first number alone! Partition the second number into tens and units.Step – 24 = First take away the tens from your first number. Then take away the units Step – 20 = 13 Step – 4 = 9 Now I know 33 – 24 = 9
24
LG: To use the split strategy to solve worded problems
1. There are 36 ducks and 35 swans on a lake. How many altogether? 2. There were 342 people in the assembly hall. 49 students from two classes left early to go to swimming lessons. How many people were left in the assembly hall? 3. Zara has 34 stuffed animals. Paris has twice as many as Zara. How many stuffed animals do the two girls have in all?
25
LG: To use the split strategy to solve worded problems
4. There are 24 students in the class. Half have brown hair and half have blonde hair. How many children do not have brown hair? 5. I have read 134 pages of the 512 pages of my book. How many more pages must I read to reach the middle?
