Our Superkids Super magazine once again gave us an area to investigate. This time we read about M.C. Escher, an artist who spent his life working to make impossible things look possible in his art. His art led us to Tessellations, which are patterns in pictures which fit together perfectly. Mrs. Sayre came into our classroom to explore Tessellations with us through the NCTM (National Council of Teachers of Mathematics) site, Illuminations. A link to this site can be found on our classroom homepage under Useful Links - Other Fun Sites - Tessellation Creator. The students really enjoyed creating their own unique patterns in their pictures. Some of the comments include: "This is fun!", "I'm definitely going to do this at home!", "I can't wait to show my parents."

Explore this site with your child and create a Tessellation with them. Some of their examples are below.

## Literacy

This week's phonics focus in Superkids was long vowel sounds in the patterns -old, -ost, -ild, -ind, and the short vowel sound in -ea. We talked about the suffixes -ful (meaning full of) and -less (meaning without). We also explored similies using like and as to compare two things.

Next week is also the last week of second quarter. We will be celebrating our AR achievements on Friday, January 22nd, with a movie about the life of Dr. Martin Luther King, Jr. Our classroom store will be open for students to spend their pennies.

## Math

In math this week we have been adding 1-digit to 2-digit numbers, and 2-digit to 2-digit numbers.

Students were introduced to 5 different Addition strategies:

• base ten blocks
• open number line
• making tens and hundreds
• decomposing
• standard algorithm without regrouping

The reason behind teaching multiple addition and subtraction strategies is not to confuse students, but rather help build their Mental Math skills so they are able to solve problems with and/or without paper. Give your student a problem, like 40 +70 or 34 + 55, and have them demonstrate solving them using each of the different strategies.

We also played math games this week that can be found on our classroom home page under Math.

• Greg Tang (Breakapart and Num Tanga)
• Sheppard Software (Fruit Splat Addition)

In IXL students should complete Addition two digits:

G.1, G.2, G.4, G.6, G.8, G.9, G.11

## AR Winners

The end of the second quarter is in sight. This week's AR prize winners are pictured below. The quarter ends on Friday, January 22nd - GO READERS!

## Miscellaneous Items:

• The form for your preference of conference times is in the Friday folder. It is due back next Friday, January 22nd.
• After school programs start next week on Tuesday, Wednesday, and Thursday. The option for 2nd grade is Study Hall. The pink slip should be brought to school on the day your child is to stay.
