[Math] 2D and 3D shapes- helpful online resources

We learned about Prism and Pyramid today. https://www.learner.org/interactives/geometry/3d_pyramids.html This website has 3D model of a different type of prisms and pyramids. It will help students to visually see and explore different shapes. (Scroll down to see the interactive image.)

[Math] Geometry

We started Geometry unit. Students' been exploring attributes of 2D shapes. (Angles, Verticies, Sides) We also discussed the idea of congruency.
We are going to also learn about 3D shapes.

Students created their own artwork using different blocks- exploring congruency, symmetry, reflection, slide, turn, and etc.

[Math] Study guide for upcoming quiz

Grade 3 Addition and Subtraction Study Guide

Date: Thursday, November 22nd 2018

- Rounding 2- and 3-digit numbers (i.e. Rounding 139 to the nearest ten is 140)

- Comparing Numbers (e.g., I know 83 is greater than 73 because 83 has 8 tens and
73 has 7 tens)

-Estimating sums and differences (23+52= ___  → 23 is rounded to 20 and 52 is rounded to
50, 20+50= 70)

- Adding and subtracting involving 3-digit numbers (i.e. 123+546, 177-58, etc.)
using a variety of strategies (including standard addition/subtraction)

- Using different strategies for solving a problem

- Find a missing number (i.e. 12- __=3)

- Problem-solving (Underline important parts of the question, show all of your
thinking clearly and include an answer sentence)

*Students can pick and choose any addition and subtraction strategies.

[Math] Online Games

We've been working on 2-3 digits addition and subtraction questions.
To support students' learning at home, I included online math game sites where students can further practice their addition and subtraction skills.

https://www.education.com/games/third-grade/ (Students can use their google email account to join and they will be able to play the game for free)

[Math] Addition and Subtraction

In math, we have been exploring different ways to add or subtract two and three digit numbers.

We learned to play "i spy" game. You can play it at home with your child- i spy the two number that adds up to 10 or two number that rounds to 30.

[Math] Number Patterns Quiz Study guide

We are going to have a math quiz next week on Oct 24, Wednesday.

Students should have an understanding of the following:

• Find missing numbers in a pattern (i.e.: 2, 5, ___,___, 14) 
• Use a pattern rule to continue the pattern  
• Find a number on a hundred chart (i.e.: find the 10th odd number on a hundred chart) 
• Identify and describe patterns on a hundred chart (i.e.: Start at 40, count by 4s-
• The number increases by 4. I noticed that one’s digits repeat: 4,8,4,8) 
• Understand the following terms: growing, shrinking, repeating patterns

[Math] Rounding

This is what we discussed in the class last week about rounding. 

We also discussed how to show our work by describing in a number line and words. 

[Math] Place Value Study Guide

Grade 3: Place Value Study Guide

Quiz Date: __Oct 4, 2018 Thursday_____________________

Students should have an understanding of the following:

• Composing and decomposing 3-digit numbers
• (i.e. 456 is 4 hundred, 5 tens, 6 ones... 5 hundreds, 7 tens and 9 ones is 579)
• Standard name: 389; Base ten name: 3 hundreds, 8 tens, 9 ones
• Showing numbers in different ways
• (i.e. 45 can be shown as 4 tens and 5 ones or 3 tens and 15 ones)
• Comparing numbers (i.e. 57 > 40... Read as: 57 is greater than 40)
• Rounding numbers to the nearest ten or hundred (i.e. Round 678 to the nearest ten: 680)
• Show how you know in a number line
• Show numbers using an exact amount of block (e.g., show 235 using exactly 19 blocks)
• *For extra practice students can visit abcya.com and play the games under the “Numbers” section

Wow Work!

We display our works on the "Wow Work" station and share with the class.

"Math about Me"
We wrote 8 numbers that were meaningful to us.
i.e. 7 -> I am 7 years old.   (3+4=7), (1x7=7) 3 -> I have 3 siblings. (1+2=3), (1x3=3)

[Math] Math is everywhere!

In order to support your child with math at home and in day-to-day life,
 the math page on our board website lists useful websites, activities
and games that you can reference and use.  Thank you for the important role
you play in the creation of confident problem solvers.

Math is everywhere!

September is a great time to start building routines at home which can support
children in developing a positive disposition towards math.
Providing opportunities at home that promote math talk can support
a child’s mathematical knowledge and understanding.  
Whether you are, shopping, cooking, playing a game, organizing,
taking a walk, or reading, there are many opportunities to highlight math in different ways.

Activities:

Grocery Shopping

Ask your child to estimate how many of a grocery item (for example, a
type of fruit or vegetable, bread or pet food) your family will need for the week.

Ask, “Why do you think that amount will be needed?”

At the end of the week, have your child count the number actually used.

Tips for Math

Build strong, positive attitudes about math. When children feel positively engaged and successful,
they are more likely to stick with an activity or a problem to find a solution.

Begin with activities that meet your child’s level of mathematical understanding.

Early success in solving problems will build your child’s confidence.

Gradually move to activities that provide more challenge for your child.

If you and your child are more comfortable in a language other than English, use it.

Your child will understand concepts better in the language that he or she knows best
