We continued Spirit Week by celebrating Crazy Sock Day and reading another Dr. Seuss book: The Lorax. Dr. Seuss sure loved to rhyme. He even made up words to make them rhyme!
Remember tomorrow is the last day of school before Winter Break and our final day of Spirit Week. It is CRAZY HAIR DAY! We will also have a surprise visitor that day.
Reminder: Tomorrow is the last day of school and we will see you back refreshed, recharged and ready to learn on January 7th, 2019.
Math
We have been talking about Number Lines in math. What is a number line? How is it used? Where do we see them? How can they help us build numbers, solve equations and visualize numbers?
We decided to make our own number line, using graph paper, rulers and pens. We decided to skip count by 5's using the blue lines of the graph paper as equal distance points and so that we would have enough room on our line to go past 100.
Number Lines
Ask me what the most challenging part of this was?
We had to review skip counting by 5's and look at the patterns we see happening on a hundreds chart when we move by 5's. What is happening with the place value when we skip count by 5's? What pattern do we see?
Practice this at home using the interactive hundreds chart. Can you see the pattern?
Today we continued working on ages questions. This time we looked at Maria from the story. She is 10 years old. We were challenged to figure out how old everyone in the family was when Maria was born?
We can use addition to get to the number:
We can use subtraction to get to the number:
We can use our personal number lines to help us to do this.
Ask me which I prefer...adding to get the answer or subtracting?
Skip counting by 10's helps us to be able to move quickly on the number line both forwards and backwards. Knowing how to get to our landmark numbers also helps up to be able to move more efficiently.
Ask me how I am figuring out these problems? How can I use the number line to do so?
