Grade 2 - Royal Oak School - Yoon: Bow Habitat - Importance of Water / Collaborating on Addition Strategies

Reminders:

1. Please remember to read, comment/sign, and return Home Journals on Monday.

2. Volunteer for Guided Reading at: volunteersignup.org/FXHFB

3. Monday, Jan. 27 – Family Literacy Day – wear PJs, Bring Stuffy & Favorite book to read with our Kindergarten buddies!

4. If possible, bring in yarn for our upcoming weaving project in art. Our class will be exploring fiber arts by creating weavings on handmade looms. Our inspiration for the weavings is tied into our study of the Arctic. Through reading Arctic stories, students have been learning about the importance and the connection that people from the Arctic have with nature. We will be using the Northern Lights as our inspiration for the weavings

Students should be using at least two colors to depict the patterns that can be seen in the Northern Lights. Colors such as lime green, navy blue, turquoise, bright pink, purple, or black would work great. If you have any of these colors and would be willing to donate them to our class, we would be incredibly appreciative!

5. Jan. 31 Non-instructional Day – No school for students in CBE schools

Learning Highlights:

In Math, we started working in groups to strategize different ways to find out the total sum of our t-shirt orders for our factories. Each group got at least 3 separate orders of t-shirts and had to figure out how many t-shirts the factory had to create. This is helping us to understand how to add 2-digit and 3-digit numbers in different ways.

This group used the base ten blocks to represent the numbers for each order...

Then, they drew it on their -shirt factory poster.

Afterwards, they started representing the tens blocks as "rolls of 10 t-shirts".

Question: What do you think the next steps should be?

This group used multiple strategies!

Try to identify the strategies: (1) t-chart, (2) stacking numbers and adding with re-grouping,

(3) drawing images of base-ten blocks, and (4) tallies.

Questions: Which strategy do you like the most? why?

Which was most efficient? Why?

Other groups tried using number lines but then realized the numbers of t-shirts in their "orders" were too many to fit onto the number line drawn, so they tried using other addition strategies to figure out the total sum...

This group illustrated their t-shirt order numbers as base-ten blocks then used the stacking method to check their total.

This group explored the stacking method and found the sum, then asked for more "orders" to challenge their ability to add 2-digit and 3-digit numbers!

Our Bow Habitat field trip was also full of activities which supplemented our study of water. We had fun activities to reinforce our understanding of the water cycle, and then did some science experiments to learn how to clean the water in our world!
