Homelink 8: understanding place value

Written by ValerieW. Posted in 2nd Grade

Monday:

Dear Parents,

In Math this week we are thinking about

t

 

 

Understanding Place Value

Students understand that ones, tens and hundreds can be taken apart in different ways.  Students see that 149 is 1 hundred, 4 tens and 9 ones.  It is also 14 tens and 9 onesComposition and decomposition of numbers are foundational skill for computation.

Our learning targets are:

  • I can represent each digit in a three-digit number using hundreds, tens, and ones.
  • I can explain the value of each digit in a three-digit number (place value).
  • I can explain the value of the zeros in a three-digit number
  • I can show the same number in another way: 36 = 3 tens and 6 ones, and 36 = 2 tens and 16 ones

Our new question for our Second Grade Homelink is:

How do you know you’re right?

Homelink 7: showing numbers on a ten frame

Homelink 7

 

Dear Parents,

This week we’re thinking about

 

 

Showing Numbers on the Ten Frame

In class we are working on fluently adding and subtracting within 20 using mental strategies. By end of Grade 2, students should be able to know from memory all sums of two one-digit numbers.  Our learning targets are:

  • I can use mental strategies (e.g., count on, make a ten) to add or subtract numbers within 20 with ease.
  • I can recall from memory all sums of two one-digit numbers.

With this Homelink, we have attached a set of Ten Frames (1 – 10 and one extra 10)  Cut these into individual ten frame cards and keep in a Ziploc baggie at home.  These are the same ones that we use in class.

  Please save the ten frames as you’ll be using them again and again!

As your child works on each activity this week, don’t forget that the most important practice is explaining!

Please help your child figure out and express which strategies he or she is using!  Ask your child to tell you WHY he or she knows that his or her  answers are correct!

Homelink 6: Odd and even

Written by ValerieW. Posted in 2nd Grade

Dear Parents,

This week we’re thinking about

Showing if a number is odd or even

In class this week, we are working on whether a group of objects (up to 20) has an odd or even number of members.  We can do this by pairing objects or counting them by 2s.  We are also working on writing an equation to express an even number as a sum of two equal addends.  Our learning targets are:

  • I can identify a group of objects as being even or odd using different strategies.
  • I can write an equation to show an even sum has the same addends (e.g., 5 + 5 = 10, 6 + 6 = 12).
  • Addends are the numbers that add up to the sum (total)

 

Get ready to explain your thinking and your math strategies!

For  second graders, explaining your thinking is the HARDEST part!!   Here is where you can really help your child by lending an ear, and helping them to verbalize the wonderful ideas that are inside their heads.

Homelink 5: numbers on the ten frame

Dear Parents,

 

 

This week we’re thinking about ten frames!

Get ready to explain your thinking and your math strategies!

***You will need counters and the double ten-frame for some of your activities this week.  Find your double ten-frame on the last page of the homework!***

Homelink 4: Math – we love it!

Written by ValerieW. Posted in 2nd Grade

Dear Parents,

This week we’re thinking about

Patterns and Numbers

Teaching children to identify and create patterns is a key element in our Second Grade math programs. A pattern is any series that repeats at least twice.   In math, numbers and objects follow a predictable pattern.  It is especially helpful for children to understand how patterns work when they learn to skip count (counting by 2s, 5s, or 10s).

 

As your child works on each activity this week, don’t forget that the MOST IMPORTANT practice (and the most neglected one) is explaining!

Look for this week’s Homelink in your child’s homework folder.  Please don’t forget to cut and glue each day’s activity!
