This week in math, students were working on solving equations by determining the missing number in an equation. For example, 21 + ___ = 26. They reviewed what an equation was (“a mathematical sentence in which the value of the left side is the same as the value of the right side”), and then practiced solving equations with a missing variable in class. They also learned how to solve problems using equations and practiced this skill as well. Students were given a practice sheet on patterns to complete at home and return on Monday. We will review the answers in class in preparation for their test next Wednesday, November 29th on patterning concepts. In addition to our work around patterns, we also played a whole class game on Monday called "Bullseye" to keep practicing our addition facts, and went on the website Prodigy to work on assigned questions.
Earlier in the week, students were also introduced to the new “Maffiti” walls throughout the school. There are three areas set up for grade 4/5, grade 6/7 and grade 8/9, where students are challenged with math problems and are asked to show their thinking in the spaces provided. After reviewing the rules and expectations around this, we went for a walk to check out the spaces. Students are encouraged to regularly check out all the Maffiti walls during break times to share, communicate, and learn as NCS mathematicians!
In science, we continued work in our new unit “Light and Shadows." Students brainstormed light sources and separated them into the categories of natural and artificial light. We discussed what the term luminescence means and discussed different types of luminescence. Students also learned about what refraction was through experiments and visuals in class. In groups, students experimented with putting a pencil and penny in a glass of water and observing the results. Some of the observations discussed were: “the pencil looks broken”, “the penny looks bigger”, “it looks like there are three pennies instead of one”, etc. We discussed how light travels in straight lines until it hits a different medium like water or a solid, which causes light to slow down and bend causing this optical illusion to our eye. We compared it to us running in a field versus running in a swimming pool—water is denser so it will slow us down a lot when we try to run through water, just like light! We also observed the refraction process in action when students bent white light using prisms into the colours of the spectrum. Students learned that white light is really a mixture of colors. Each colour has a different wavelength and is bent by the prism at a slightly different angle, which separates the colours into a rainbow. We watched a fun video about how to remember the order of the colors, which I've included below. They also worked on a page in their visual journals to document their learning of this concept.
Enjoy your weekend—go Stamps go!!
