Math Quiz on Monday

Students completed a review today and you can ask them about the math quiz on Monday. The material is listed in the blog post before this one. For some fun math practice your child can go to

www.sheppardsoftware.com and choose the math games section. From there they will find many different games that focus on Place Value, mental math strategies, addition and subtraction. This is a great way to reinforce the concepts that we have studied in class.

Next week we will be moving on to multiplication strategies.

Math Review

We have a test on Monday – parents, here is some information on material that we have covered.

Math Review

 

Place Value:

Millions Hundred Thousands Ten Thousands Thousands Hundreds Tens Ones
8 4 6 7 2 5 1

 

We say: 8 million 4 hundred 67 thousand 2 hundred 51 (8 467 251)

We can write it in expanded form: 8 000 000 + 400 000 + 60 000+ 7 000 + 200 + 50 + 1

Estimating:

Remember: “ If it’s 5 or above, give it a shove; if it’s 4 or below let it go”

So….. 0,1,2,3,4 rounds down

And….5,6,7,8,9 rounds up

For example: 

Round to the nearest 10:

469 would be 470 because we look at the digit in the ones column and then round the digit in the 10s place. The digit in the ones column in this case is 9 so we round up. We round the 6 to a 7 (give it a shove) because it’s in the tens place.

462 would be 460 because we look at the digit in the ones column and then round the digit in the 10s place. The digit in the ones column in this case is 2 so we round down. We round the 6 to a 6 (let it go) because it’s in the tens place.

Round to the nearest 100:

469 would be 500 because we look at the digit in the tens column and then round the digit in the hundreds place. The digit in the tens column in this case is 6 so we round up. We round the 4 to a 5 (give it a shove) because it’s in the hundreds place.

432 would be 400 because we look at the digit in the tens column and then round the digit in the hundreds place. The digit in the tens column in this case is 3 so we round down. We round the 4 to a 4 (let it go) because it’s in the hundreds place.

 

 

Round to the nearest 1000:

2843 would be 3000 because we look at the digit in the hundreds column and then round the digit in the thousands place. The digit in the hundreds column in this case is 8 so we round up. We round the 2 to a 3 (give it a shove) because it’s in the thousands place.

2143 would be 2000 because we look at the digit in the hundreds column and then round the digit in the thousands place. The digit in the hundreds column in this case is 1 so we round down. We round the 2 to a 2 (let it go) because it’s in the thousands place.

 

Mental Math Strategies:

Doubles: 5+5, 12+12 etc

Double plus 1: 5+6= 5+5+1 (so if you know 5+5 you can easily know 5+6)

Doubles plus 2: 5+7= 5+5 +2 (so, if you know 5+5 you can easily know 5+7)

Tens partners: 1+9, 2+8, 3+7, 4+6, 5+5 etc   These can also be used in double digit addition, for example: 24+16 (we know 20+10 is 30 and if we know our tens partners, we know 4+6 is 10 so 30+10 = 40!

The goal is to be able to use these mental math strategies in larger math computation questions to speed the process up.

Leadership and Rock Block

This week the Leadership students are working on coming up with a proposal to present to the rest of the student body. The theme of this proposal is “Giving back to our community” and students have been asked to come up with something that we can do as a school to help those in Victoria who are less fortunate.  Some of the ideas that they are working on are: socks for the homeless, coats for kids, sponsoring a family for Christmas etc. It’s great to see our students wanting to make a change in our local community.

Rock Block is well underway and students are participating in a variety of activities from Learning Italian to Building a Business Plan. We have two more weeks of Rock Block (always on Wednesday afternoon) for this session. Students will have the opportunity to make another Rock Block Selection in February and then again in the Spring.

This Friday we will be having our annual Remembrance Day Service at 10:45. We are encouraging students in Cadets to wear their uniforms to this event.

In my math group we have been working on building some mental math strategies. Having strong mental math abilities supports students in real world applications. If you can add and subtract (and multiply and divide) in your head you can complete tasks much more quickly. Some of the strategies that we have been building so far are:

Doubles: 5+5, 12+12 etc

Double plus 1: 5+6= 5+5+1 (so if you know 5+5 you can easily know 5+6)

Doubles plus 2: 5+7= 5+5 +2 (so, if you know 5+5 you can easily know 5+7)

Tens partners: 1+9, 2+8, 3+7, 4+6, 5+5 etc   These can also be used in double digit addition, for example: 24+16 (we know 20+10 is 30 and if we know our tens partners, we know 4+6 is 10 so 30+10 = 40!

We will be working on more mental math strategies including subtraction, multiplication and division each week on our shorter Wednesday math block.

In our longer Monday and Friday blocks we are beginning a unit on solving problems involving larger numbers using technology.Fun times!
