## This Week in Math (May 28 – June 1)

This week, we are being introduced to the concept of ROUNDING to the nearest ten.

Students can use number lines to physically see which ten their number is closest to. It can sometimes be difficult to know where a number is relative to the tens. Students can use a Hundred Chart to find the number OR they can draw out a number line by counting forward and backward.

Practice your 2-point shots with this rounding game!

## This Week in Math (May 14th)

This week, we are finsihign up our chapter on subtraction with regrouping and reviewing these concepts from grade one:

#### 2) Increasing vs. Decreasing

2, 55, 180, 556

899, 765, 456, 32, 3

## This week we are learning how to add two-digit numbers that require REGROUPING.

REGROUPING is what you may have learned as “carrying”. However, in order to understand the concept, we are not simply putting a little bitty one on top of the next column. In REGROUPING, we draw out the numbers using base ten representation and circle when our ones create a “ten”. Then we can count our tens and our ones.

Check out this fantastic teaching video to understand the concept of REGROUPING:

Once you understand the process, it is time for some practice!!!

For Parents: This page gives a detailed explanation of how students learn addition, with good visuals to understand why it is taught a certain way.

## This week in math: Review

We are reviewing everything from February and March this week, which includes:

(1) Quickly adding and subtracting sums up to 20

(2) Reading a thermometer and choosing the matching season for the temperature

(3) Determining the Missing Term in an addition or subtraction up to 2-digits

Examples:

22 + ____ = 46

______ – 31 = 24

I highly encourage students to practice their Doubles and their Doubles Plus 1 facts this week. Here are some resources:

Doubles Flashcards

Doubles plus/minus 1 Flashcards

IXL practice questions

Here are some practice questions for Missing Term:

2-digit subtraction

## This Week in Math (January 29th – Feb 2nd)

This week we are practicing addition and subtraction facts up to 20 as well as the various strategies to help us.

### Then we are focusing on MAKING TEN

Students should continue to practice on Reflex Math and with flashcards.

## Amphibians

This week we are learning all about Amphibians!

## This week is Math (January 15th): Telling Time

This week in math we will be covering:

• Telling time to the hour, half hour and quarter hour
• Writing time in analogue and digital forms
• Estimating time of day for various events (ie; waking up, breakfast, lunch, dinner, bedtime)
• Understanding that there are 60 seconds to the minute, 60 minutes to the hour and 24 hours to the day.
• Determining the duration of elapsed time to the hour and half hour

Below are some helpful videos to practice the above skills at home:

Students can also practice telling time on IXL on the following tabs.

P.1, P.2, P.3, P.4, P.5, P.6, p.7, p.8, p.9

Here is a fun games to practice elapsed time:

Practice Elapsed time by the hour

## This Week In Math (December 4th) – Adding and Subtracting

This week in Math, we are working on 2-digit addition and subtraction WITHOUT “carrying” (though the term is regrouping). For example…

To support this skill, students should review their addition facts as well as practice the 2-digit addition skill. In school, we are using base-ten blocks to help organize our thoughts.

Here are some games to practice with at home:

This video is a FANTASTIC and quick lesson for students and parents alike:

For additional practice, try LEVEL 4 and LEVEL 6 of this computer game:

## This Week in Math (Nov 27): 3d Shapes

This week, we are transitioning from 2D Shapes to 3D Shapes. We are reviewing the following shapes and discussing the 2D shapes we can find in their faces.

Cube
Triangular Pyramid
Square Pyramid
Triangular Prism
Square Prism
Rectangular Prism
Sphere
Cone
Cylinder

For fun at home, check out this video to review some of the 3D Shapes!

As a fun activity at home, students can print out these nets and fold them into 3D Shapes.

## This Week in Math (November 6th – 10th)

This week we are practicing counting on from a 2-digit number using groupings of 10s, 5s and 1s. Here is an example problem:

To be successful with this skill, students must practice their abilities to count on from any number by 10s and to skip count using a hundred chart.

Here are 3 fun computer games to practice counting on by 10:
