Hello! We have been busy in second grade getting ready for the end of the year, completing all of our required assessments, and learning everything we need to learn before moving onto third grade! This week, we have been working with introductory lessons to multiplication and division, focusing on equal groups. We already know that we use addition to put things together or make bigger numbers, and we use subtraction to take things away or make smaller numbers. This week we are learning that we can also use multiplication to quickly make bigger numbers and division to quickly make smaller numbers. Below are the videos we watched today to help us learn the basics of division — dividing our total number into equal groups. Happy Almost Summer!
This week we will have our chapter 6 test in math, which focuses on 3-digit addition and subtraction with and without regrouping (“borrowing”)! Here is a fun video we watched today that gives us a nice trick to remember that “if the number on top is SMALLER than below, it’s time to go with the regrouping flow” when we are subtracting.
Upon returning from our fall break, we began chapter 5 in Go Math! This chapter focuses on subtraction with regrouping. I was excited to introduce this educational song, with helpful rhymes in it, to our class yesterday!
Hello! I hope you are feeling well-rested, as am I, after the long holiday weekend.
We are now officially on schedule and doing formal ELA and math lessons each day in school. Today, we did a read-aloud of our story Henry and Mudge and discussed the jobs of an author and an illustrator. Remember: Scholars must be familiar with this story, as we have our 40-question ELA test this Friday, and 10 of those questions are on story comprehension. Our centers activities that we will be doing each day will help us review the story themes, our phonics (short “a” and short i sounds), grammar (subjects–WHO? and predicates–DID WHAT?), and our language skill (alphabetical order) this week.
In math, we had fun reviewing our doubles facts! Scholars are learning that they can use a doubles addition sentence (i.e., 6 + 6 = 12) to solve a near-doubles addition problem (i.e., 5 + 6 = 11). We also began learning about the following vocabulary words in math today: sum, difference, greater than, less than, addends. Feel free to watch the fun doubles-fact video below with your scholar this week! You can also find several doubles worksheets that you can download and print by clicking HERE.
Our “Go Word” for this week is: VERB. Today we learned that a verb can show action (run, jump, hop, skip) or a state of being (am, is, are, was, were).
This week in math, we are learning how to break apart numbers to subtract. To assist my students in doing this, I’ve uploaded a “120 chart” on my website. Students may use this as a visual aide to assist them with doing breaking apart numbers to subtract and, eventually, my hope is that students will be able to visualize this chart in their head, so that they may solve problems that may seem complicated using only “mental math”.
Using the 120 chart to solve a problem like “50 – 37 = ?” my students are expected to know how to:
- Break apart 37 into 7 ones and 3 tens
- Find 50 on the hundred chart and point to it
- “Jump back” 3 tens and 7 ones
- Land on the number 13, which is the correct answer to the problem “50 – 37 = ?”
Please find the 120 chart here: https://missmcwoodson.files.wordpress.com/2016/01/120chart.pdf or in the right column on my website, under “Take Home Binder”.
I came across this video earlier today, and I was pleasantly surprised when I heard the voice of Genevieve Goings of Choo Choo Soul, who I know from a freeze dance song I frequently use for my children’s dance classes. I was excited to find Genevieve’s educational video of counting around the clock by fives, which is something my second graders and I practice each day during our math “calendar routines” and spiral review. I will be sure to show them this video before calendar routines when we get back from the winter beak!
