*I still require 1 or 2 parents for our Glenbow Museum field trip on Monday, December 3rd!!
Please THINK TWICE before going ON THE ICE
⬇
Parents, we have had reports of youth in our community venturing out onto the partially frozen pond. This is, of course, a safety concern as the pond does not typically freeze consistently enough to safely allow people to access the ice.
We are asking that you please have a discussion with your children about Ice Safety and how to determine when an icy surface is a safe place to play. An excellent resource (with notes and videos) for this discussion can be found through the Canadian Red Cross website at:
Thank you for keeping our students safe as they explore the community this winter,
Parent Conferences
Thank you to all the wonderful families I had the chance to meet with to discuss student learning. Thank you for understanding our students work and processes for learning by checking out my blog on Tuesday's and Friday's.
Math Inquiry:
Grocery Store, Stamps and Measuring Strips!
The focus of this inquiry is the introduction and early development of multiplication. Students find ways to use grouped structures in a real-world context. Initially, multiplication notation is not our focus, but efficient grouping is. Students are encouraged to make groups (and groups of groups) find efficient ways to deal with repeated addition and determine totals.
*Please note the examples below are meant for parents to understand the Key Ideas, and not necessarily numbers that our Grade 3's will be working with :))
KEY Multiplication terms and ideas:
Factors: are numbers we can multiply together to get another number. Example: 2 and 3 are factors of 6 because 2 × 3 = 6. A number can have MANY factors!
Product: Factor 1 * Factor 2 = Product
The product is the result or answer of multiplying the multiplicand by the multiplier.
Multiplier or Multiplicator and Multiplicand:
Distributive property of multiplication: factors can be broken apart and distributed to make partial products, which can then be added together to produce the product of the original factors.
Commutative property of multiplication: a * b = b * a
Arrays will be used to demonstrate what can be called the *Turn-around rule!*
Repeated Addition can be regrouped: calculating the totals of long strings of repeated addition can eventually be tedious and not efficient.
Skip-Counting: a means of efficiently counting groups of equal amounts
Doubling and Doubling some more: an early strategy for counting groups in a funnel approach
Arrays: An arrangement of objects, pictures, or numbers in columns and rows is called an array. Arrays are useful representations of multiplication concepts.
Partial Products: Students begin to make partial products- they use a fact they know to make another. For example, they might reason that if 5 packages of paper towels (4 rolls in a package) contain 32. Here they are finally making the group of a unit (unitizing) and adding it or subtracting it as needed.
Open Number-Line: A student strategy to visually represent equal groups being added repeatedly that mimics a multiplicative equation.
Geologist Expert/Turtle Mountain
We met with Dr. Todd Shipman, head of the Alberta Geological Survey and an EXPERT on Turtle Mountain (at the Frank Slide)! We were excited to have him do some MythBusting on why the rock slide actually happened, and modern technological means of surveying the mountain for potential future rock slides. Students have written a "Scientific Conclusion" based on what he shared with them in their 1903 Field Journals and Reports!
We looked at the 3D Mapping of Turtle mountain using a laser-guided track.
