This week we have been solving money problems. Remember to use column addition to find the total and then a number line to find the change.
If you get really stuck, tell Mr Brown on Monday.
Some of you will be practising your 3 digit subtraction on a number line.
This is the method we use.
This week is a puzzle. You should be ok if you follow the instructions. If you want a challenge, you could also try the homework from other groups.
But if you get really stuck, tell Mr Brown on Monday.
This week is all about using column addition to add. Cylinders group have slightly easier numbers but they could try the harder questions as well if they like.
I've included a screen shot of how we teach this in class.
This week we are revising subtraction on a number line. This screen shot shows the method we use in class for 3 digits - 2 digits.
The method for 3 digits - 3 digits is the same but instead of jumping to 100, we jump to the next 100.
It's about time!
This week you have to find out about various units of time. If you know, you can write them in. If not, you can ask parents or other people, you can use the internet or you can use books.
For the part about months - learn and use the rhyme or try the knuckle method.
There is also an extra challenge if you fancy a go at that.
This week is a number problem. The numbers on each side must add up to the number in the centre.
The first one has been done for you and there is a hint.
One of the best ideas for puzzles like this is to have number cards that you can move around. This saves you having to write it out every time and you can swap numbers easily.
Your number cards will also be great for practising your Learn Its.
There are puzzles to solve this week.
The key is deciding which order to work out the value of the salamanders.
If you get stuck, this is how you solve the Spheres, Pyramids and Cylinders puzzle.
Start with the row that has four of the same slalamander - the third row. If 4 of them add to 12, each one must be 3. Write the value of this salamander on the puzzle.
Next find a line where there is only one missing type of salamander. The top row. This row will now be ? + 3 + ? 3 = 10. So the 2 missing salamanders add to 4. They must be 2. Write these on.
Then the 2nd line. ? + 3 + 2 + ? = 13. So the 2 missing salamanders add to 8. They must be 4. Write these on.
Last, the 4th line. ? + 4 + ? + ? = 19. So the 3 missing salamanders add to 15. They must be 5. Write these on.
Finally, check all the lines add up to the correct totals.
The Cubes and Cuboids puzzle works the same way.
If you are still stuck - ask Mr Brown on Monday.
There are all sorts of other maths puzzles on www.math-salamanders.com
There are 2 versions, you could have a go at both if you like.
Although these look different to other maths we've done, it's really just missing number calculations.
The key is to find which ones are possible (with only one missing number) and do those first.
You could use your switchers and fact families
4 + ? = 7
? + 4 = 7
7 - ? = 4
7 - 4 = ?
We have been converting grams to kilograms and grams and kilograms using a decimal point.
Remember there are 1000g in 1kg.
4500g = 4kg 500g = 4.5kg.
This week's homework involves reading numbers on a number line. The tricky bit will be working out what the intervals are or "what it goes up in". Trial and error works well: try an interval and count along the line, if you get to the wrong number at the end, work out whether the interval you chose is too large or too small and then try a different interval.
This week is a puzzle. It's a bit like a wordsearch but instead of finding words, you have to find a line of numbers which add to 30. Find as many as you can but there are 10 possible answers.
This week's homework is problem solving. We haven't done this type of problem in class yet - we will look at it on Monday.
The key to problems like this is to make it real. So you could draw and cut out some stamps with the price on them and then add them up until you find the stamps which make up the total.
This week is all about money problems. We have done some in class, so follow all your Remember Tos, like we did in this week's lessons. Good Luck.
In class we use column addition to add and number lines to find change.
Maths homework Mr Brown's group 10.11.17
We have been working on adding ones, tens and hundreds in class.
This is a fantastic online resource to practise with.
