Online learning activities - Week 7:
Follow up from today’s lesson:
This week we have combined spicy and ghost chilli due to Whaea Sharon and Whaea Trudi being at bubble school. There will be two online workshops offered this week to support your learning.
We are going to continue to focus on addition and subtractions skills, particularly questions where you can use your multiplication skills to help solve addition problems.
Start by warming your brain up with some basic facts on Prototec. I suggest doing the tables 0-10 challenge.

Look at these sequences of numbers and add them together, remember to look for a pattern.
1) 1, 3, 5, 7, 9, 11
2) 1/4, 2/4, 3/4, 1, 1 1/4, 1 2/4, 1 3/4
3) 0.3, 0.6, 0.9, 1.2, 1.5, 1.8, 2.1
1) 1, 3, 5, 7, 9, 11
2) 1/4, 2/4, 3/4, 1, 1 1/4, 1 2/4, 1 3/4
3) 0.3, 0.6, 0.9, 1.2, 1.5, 1.8, 2.1
Follow Up:
1a) How many pairs of numbers that add together to make 21 can you make from the numbers 1 - 20?
1b) Show how you could use these pairs to find the total of all the whole numbers from 1 - 20.
1c) Discuss with someone in your bubble how you found the answer and why it works.
2) Find the answers to these sums using multiplication. Remember to look for patterns. Show your working.
a) 1 + 2 + 3 + ... + 29 + 30
b) 1 + 2 + 3 + ... + 45 + 46
c) 1 + 2 + 3 + ... + 57 + 58
d) 11 + 12 + 13 + ... + 49 + 50
e) 41 + 42 + 43 + ... + 100
f) 164 + 165 + 166 + ... + 200
3) Charlie laid some paving stones on rows in the school courtyard. The first row had 50 paving stones and each row after that had 1 more paving stone. The final row had 87 paving stones. How many paving stones did Charlie lay altogether?

Place Value Practice:
Lockdown Activities - Week 6
This week we are focusing on place value. Remember, do as much or as little as you like! We will be covering the following:
- Place Value - Quiz
- Saving hundreds
- Tidy numbers and Jumping the Number line
- Don't subtract... add!
- When One Number Is Near a Hundred
Warm up - Quiz (click on the image)
Task 1. Saving hundreds
We are learning to solve addition and subtraction problems by using place value partitioning.
|
Practice these:
|
Task 2. Jumping the Number line
We are learning to solve addition and subtraction problems with tidy numbers.
|
Draw a number line and practice these:
|
Task 3. Don't subtract... add!
We are learning to use addition to find the answer to subtraction problems
|
Practice these:Hope solves 63 – 38 = ? by seeing that 38 +____ = 63 has the same answer. She says the answer is 2 + 23 = 25.
For these problems rewrite as an addition problem and then use Hope's addition method to work out these subtractions.
|
Task 4. Don't subtract... add! Word problems
We are learning to use addition to find the answer to subtraction problems
Task 5. When One Number Is Near a Hundred
We are learning to solve addition and subtraction problems by compensating with tidy numbers.

Practice these:

Lockdown Activities - Week 5
This week we are focusing on place value. Remember, do as much or as little as you like! We will be covering the following:
- How many tens and hundreds are in any whole number and recognises that ten tenths make one.
- How to round numbers to the nearest 10, 100 and 1000.
- Groups within 1000 and groupings of 2, 5, and 10 in numbers up to 100.
Task 1.
We are learning to find how many tens and hundreds are in any whole number
Look at these steps carefully to help you work out how many tens and hundreds are in any whole number...
Task 2.
We are learning to find how many tens and hundreds are in any whole number
Task 3.
We are learning to recognise that tenths make one.
Task 4.
We are learning to round numbers to the nearest 10, 100 and 1000.
Take a look at this video to work out how to round numbers.
Now give these a go!
Task 5.
We are learning to round numbers to the nearest 10, 100 and 1000.
Optional Rounding Game: You will need a set of playing cards and an adult!
What you need:
A deck of cards with the face cards and jokers removed (aces count as 1s and 10s count as 0s).
What to do:
Deal 2 cards in a row. This represents a 2-digit number (eg. 36).
- Ask your child to read you the number.
- Ask your child to round the number to the nearest 10
Deal 3 cards in a row. This represents a 3-digit number (eg. 364).
- Ask your child to read you the number.
- Ask your child to round the number to the nearest 100
Deal 4 cards in a row. This represents a 4-digit number (eg. 3647).
- Ask your child to read you the number.
- Ask your child to round the number to the nearest 1000
You round to whichever number is closest, but if the digit being rounded is a 5 then you round up, rather than down. For
example 4125 rounded to the nearest 10 is 4130, not 4120.
