We will be using Geo-boards and Tangrams to learn all about 2-figures, parallel lines,
right angles and more. I will post more video's, information pages and songs to assist
your child's learning. I page of terms will come home on Tuesday. (Yet we have not
covered all of the information on the page.)
We have started our 2-D geometry unit and are learning and reviewing many different kinds of
polygons. Here is a video to review some 2-D figures and learn a few new ones. I will post the
success criteria.
This video is great to show rounding to the nearest hundred. It also is good
for explaining how rounding helps us estimate. It also explains about benchmarks.
Some students were still having some difficulty understanding the rounding
to the nearest 10. We will do some review and I think this video will help all
students with rounding.
Please watch this video and practice making some of your own number lines.
We will do more number lines in gym class and also with our gr. 7 math buddies.
When you try rounding to the nearest 10 or 100 you need to go back to the general rounding rules. Remember to always circle the place value column that you are rounding.
So if you are rounding to the nearest 100, circle the hundreds column and underline the ten, decide if it is 0-4 or 5-9 and decide which 100 it is closest too! Why do we round numbers? How does it help us?
(It helps us estimate, guess and check to ensure we did it correctly, or sometimes to make sure we have enough money or even candy for Halloween.) It is a very useful skill to have in life.
Rounding to the nearest 100:
You can see here how the numbers work in the place value chart, this is called expanded form. We are learning to use the cups and add a cup, to make the place value or numbers grow as your child is ready.
We are using base ten blocks in the picture below, and we are using the place value cup game that we made to help us too.
Please remember to discuss the greater thatn and less than symbols with your child too.
Please discuss the General Rounding Rules:
This is one of the main learning goals this week. We
will be playing math games and using math tools
to assist our learning with rounding rules.
This picture is a good example of how to help
your child understand how to round any number
as long as you remember to circle the number
in the place value chart that you are trying to estimate
or round to the nearest 10, 100, or 1000.
After discussing this concept they can go back and watch the rounding video. Enjoy the video!
Place Value Practice
More Math Games we will be playing next week...
One of the games we will play when we are done our work or use as a warm up is Math Power Towers. We have Doubles, Doubles plus 1, and subtraction games. Plus Guess Who games too!
We will play a bunch of place value games with our math buddies soon. Our math buddies will be Mr. Pranger 's grade 7 class. They will be coming to help us learn once a week! We will play math games once a month and the other 3 weeks they will come and work with us on explaining our thinking, when we work on a math problem. This is such a great opportunity!!!
New information: While learning about place value we will be discussing the size of the numbers and as a result the less than, greater than , equal to and not equal to symbols play a big role in communicating their understanding.
Place Value Charts and Base 10 Blocks are going to be going to help us explain our thinking for this unit!
We are learning about number sense!
These are the "I can " statements that we are learning about in the next month. We will be learning about writing and demonstrating numbers from 1 to 999. We will be learning by playing games, using many different math tools and to learn more efficient strategies to explain their thinking. For example, making an organize list. I will be posting ideas to explain these "I can" statements.
We are learning about Place Value:
We have been learning all about the strategies we need to use when we get a multiple choice question.
The student that is finding this a challenge can draw the tens and ones with base 10 blocks.
If a student is ready they can use the greater that and less than symbol.
43>24
This is a pyramid card game. The students flip a card in the first row and them read it. They can play against a partner and then they compare the numbers. The student with the greatest number gets a point. Then both flip the cards in the second row of the pyramid. They read the number, tell how many tens, and ones. Then state which number is the greatest. The student with the largest number gets a point. This happens with the third and forth rows in the card pyramid.
For example: a student that gets 4 tens, 3 ones has 43 which is greater than has 2 tens, 4 ones, 24.
We are learning all about Multiple Choice!
It can be a hard strategy to learn, we want to think through our choice,and not rush and guess
the answer quickly. This will help for the CCAT test they will write next week. This test is for gifted screening. A letter will be coming home very soon to inform you of the test.
The Math Math, and the Thinking Math Strategy Mat came home today. They are for you and your child to use for any math homework or math game or challenge that comes home. These will be useful for Grade 3 and for many years in the future. Please keep them in a safe place. They were stapled to a copy of the the October class newsletter that was sent home today. The newsletter has been designed for the website and looks much better on the website that on paper.
Patterning!
This Unit will help us to find and describe geometric and numerical patterns in our lives.
At the end of this Unit in Grade 3 your child:
can identify repeating patterns.
can find the pattern core.
can tell which attributes change.
can tell how attributes change.
can identify increasing and decreasing patterns
can identify the pattern rule.
can use T-tables to solve problems.
can communicate about patterns.
Key Words for this Unit:
Repeating Pattern: a pattern with a core that repeats.
ABABABAB...
Pattern Core: the smallest part of a pattern that repeats.
ABABABAB...
Attribute: a way to describe a figure (colour, shape, size, direction, thickness)
The letters are changing by A, B repeat.
Pattern Rule: a description about a pattern that tells how to make or extend the pattern.
Start with purple AB, repeat.
Increasing Pattern: a pattern that grows.
1, 3, 5, 7, 9, 11... (Start at 1, add 2 each time).
Decreasing Pattern: a pattern that shrinks.
100, 90, 80, 70, 60... ( Start at 100, subtract 10 each time).
