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
