Games - 100 or Bust - closest to 100 using cards 1-9, and can put in the tens or ones.
Numbers game - using digits to make a certain number.
Another Warm Up - Give students 3 cards/or put on the board.
- student to make biggest number, and write it in numbers and words.
- Make/draw it with equipment.
- Say
- Round to nearest number (10’s, 100’s etc).
- Order it (make 4 new numbers with same card and then order them from small to big)
- Dictation
- Expand it - 400 + 20 + 1
- Then add and subtract 30 etc.
- How many more would you need to make 10?
Warm ups - 199 + 24 = 99 + 50 =
39 + 15 etc 19 + 19 =
Kids love building with yellow blocks. Make a small structure and get them to count how many blocks. Write out in modelling books.
Jo Knox modelling with small group. Do Diagnostic first. Then check prior knowledge. Co-create WALT at the end with them. What did we do?
Think pair share within the group.
Go back to diagnostic if kids not too tired/over it and you think it would be worthwhile.
Reversibility
1002 - 987
Making tidy numbers
Decimals
When multiplying by 10 everything jumps up one, into the 10’s, 100’s, 1000’s etc.
Must understand fractions well first.
Could split Year 3’s and Year 4’s.
Candy bars for 10ths, wrap up 10 breakable cubes together.
Decimats Decimats NZ Maths resource
Blue pipes - one whole licorice -
If this is one whole piece, what is this (10th)
Students will write 1/10 or one tenth.
Put place value house up and the decimal point.
How many ones do I need to make a 10? 10. How many 10’s do I need to make 100? 10. Etc. Show on PV house.
After the decimal point is not whole numbers
After this, how many pieces make a whole one? This is our tenths column.
How many whole licorice sticks do I have? 0. How many tenths? 0.1
What does half look like? One half = 5/10 or 5 tenths.
How many whole ones? 0. How many tenths - 0.5
How can we show one quarter? Can we?
Get the 100ths. How many tenths? How many hundredths? 2 tenths, 5 hundredths.
Make 0.4. Make 0.32 Make 1.04 Make 0.6
Have students make them, and then compare them. Who has the most licorice? Who has the least. Show the numbers too on the board so they can see the numbers.
Practise game - Decimal Rocket - 7 spaces.
7 spaces with 0. on the side. Highest to lowest at bottom. Roll 3 dice, then 2, then 1. So the digits they enter might be 2, 5, 4, then 5, 6, and then 7. This makes them think about if 0.76 is higher or lower than 0.7
What is 0.54 - picture what that looks like.
Now picture 0.3. What do you picture now?
What is 0.54 + 0.3
This has now moved into imaging.
3.6 - 2.98 Use equipment. One person holds 3.6. Give 3 to a friend. How many do they owe you? 0.2
Book - One is a snail, ten is a crab - Cool for algebra intro.
Have students create their own creatures eg. 8 eyes, 5 hands, 2 legs etc. So 8 of these animals would have how many eyes, legs, hands etc?
Make books you read link to maths problems.
Biscuits loves to eat cookies. He ate 5 cookies everyday for a 6 days. But on Sunday he ate 6. How many did he eat during the week?
