In math, we went over the practice sheet given out in class last week before students wrote their test on addition and subtraction concepts on Wednesday. We played some more subtraction games early in the week such as “What’s the Difference?” and “Subtraction War.” They finished their "Mad Minute" booklets with the majority of students demonstrating an improvement in their recall of their basic subtraction facts. We also started work on multiplication concepts and strategies in class. Students collaborated in small groups and were asked the question “What is multiplication?” They were asked to brainstorm and record in words and visuals what multiplication is; strategies and tips they knew for remembering their facts, signs and vocabulary for multiplication; and any facts they could recall. Once they brainstormed and wrote all their information down, students went on a gallery walk to tour other group’s ideas. They remembered a lot from last year and had some really good information and strategies to share! Students also practiced their multiplication facts by playing interactive games using the laptops. The games are located in the sidebar and can be used to practice at home. In science this week, students continued our learning about shadows and how “a shadow is the darkness that is cast/made when light shines on an opaque object.” Students conducted an experiment in class by creating shadows and then changing the direction of their light source to observe what happened to the size and direction of their shadows. We watched some neat shadow puppet performances (I've attached one below that the students really enjoyed!). Many of the students were very talented in creating their own shadow puppets too! We are wrapping up "Light and Shadows", and students will write a unit test on Tuesday, January 30th. A study guide went home Thursday in preparation for their upcoming test. Students were encouraged to take home their science duotang and visual journal to help them study (reading previous blog posts for “Light and Shadows” is another tip we went over). I’ve attached the study guide below in case it was misplaced. We also toured the 2nd Annual Nose Creek Science Fair Thursday afternoon and were impressed by all the great science-related projects produced by our grade 6 and 7 Kodiaks. Light & Shadows Study Guide Enjoy the last weekend of January! —Ms. Jagger In math this week, students did a lot of work around solving problems associated with addition and subtraction. We went over key words and phrases that you’ll often see in addition and subtraction word problems (for example in addition: How many are there altogether?, How many are there in all?, What is the total?, etc.; and for example in subtraction: How many are left?, How many more are needed?, How many fewer?, etc.). We also went over in detail four steps to help in solving problems (understanding the problem, making a plan, carrying out the plan, and looking back). We used this information to model and complete some problems as a class. Then, students practiced their skills on some problems either independently or with a partner(s). They used highlighters to highlight the key information and numbers they needed to solve the problem. Many of the problems were multi-step so this strategy helped them determine what operation was required and in what order they needed to solve it. We also continued to work on subtracting multi-digit numbers with regrouping. We learned a strategy in which you rename the minuend to make the subtraction of numbers much easier (see the example below). We also played the subtraction game “Black Hole” to continue to practice our basic facts. A practice sheet went home yesterday for students to complete in anticipation of an addition and subtraction test next Wednesday, January 24th. The practice sheet is due Monday so we can go over it in class. I’ve attached it below in case it is lost or misplaced. Addition & Subtraction Practice Sheet In science, we started work around shadow concepts. Students were given a set of questions relating to shadows and were asked to research the answers given the websites provided. Some of the websites were interactive and students needed to complete the tasks to see how shadows are created, and how the position and strength of a light source affects a shadow. We also looked at some neat optical illusions in class. Illusions trick us into perceiving something differently than it actually exists, so what we see does not correspond to physical reality. Optical illusions can use colour, light and patterns to create images that can be deceptive or misleading to our brains. The information gathered by the eye is processed by the brain, creating a perception that in reality does not match the true image. It was interesting to see how some students saw one thing in a picture, while others saw something entirely different in the same picture!
Have a wonderful and restful weekend! —Ms. Jagger Use the following websites below to research and answer questions relating to shadows:

It’s hard to believe that 2018 is here! It was great to see students return from their break rested and eager to continue our learning of math and science concepts.
In math this week, students worked on their subtraction skills and strategies in class. We started the week by reviewing multi-digit addition strategies from before the break; working on the journal question, “12 is the difference. What is the question?” and playing the game “Complimentary Fish”—a card game that works on adding & subtracting combinations. This week we also practiced estimating differences to 10 000, and learned a mental math strategy to use when subtracting numbers close to hundreds or thousands. Students additionally learned about regrouping when subtracting multi-digit numbers and did some practice questions using virtual manipulatives on the laptops. Having a visual showing the regrouping process with base ten blocks was very helpful in understanding how this process works (the website we used is in the post below). Students continued working on their subtraction number facts in their "Mad Minute" booklets. Regular practice of basic facts at home is strongly encouraged. In science, students learned about the structure of the eye, how we see objects, and how to keep our eyes safe. We watched and discussed some great videos on the structure of the eye, how it works, and how to take care of our eyes. One important point we learned is to never look directly at the sun or any bright object as this can permanently damage your eyesight. Students completed a page in their visual journals with some important points on how to keep our eyes healthy and safe.
