Week of Dec. 4th

 


This week in math, we have transitioned from adding three and four-digit numbers with and without regrouping to learning how to subtract with regrouping using 1 hundred blocks as 10 ten blocks, or 1 tens block as ten ones blocks or both. We learned how to use base ten sketches and the standard algorithm. As we moved into subtraction, we took some time to review the importance of understanding what a fact family is. A fact family is a group of math facts using the same numbers. In the case of addition/subtraction, you can use three numbers and get four facts. For example, you can form a fact family using the three numbers 18,22 and 4: 18+4=22, 4+18=22, 22-18=4 and 22-4=18. We can use fact families, to reinforce or learn the connection between addition and subtraction and to help memorize the basic addition and subtraction facts. If your child has been away over the last few weeks, I have put in Google Classrooms some slides that will help you review with your child the concepts that we have been learning as they relate to regrouping and adding numbers with regrouping up to three- and four-digit numbers. 


In class, the students have been busy researching a specific food chain. This research includes understanding the producer, the consumer, and the food chain’s decomposer. At the same time, researching, we have been learning how to use our own words, taking notes that briefly summarize the most important parts of each source while trying to be clear and concise by omitting details that are not relevant to the topic. In addition, we have connected this project to include literacy as we have been busy preparing a script and practicing reading it out loud to begin creating a claymation stop motion video. We are excited to continue to share this great project with you in the coming weeks.

A big thank you to all of our volunteers who joined us for Aggie Days this week. The students had a wonderful time learning all about the agricultural climate in Alberta and gaining an appreciation for the hard work that it takes behind the scene to provide food for us to eat.  In Math this week was to learn how to skip count to divide. We discovered how to skip count on a number line, skip count using our fingers and that we can divide by sharing the total number of items and the number of times in each set.  To use a number line we considered, what number is being divided? (20) How can you tell from the picture? (20 is where the arrows end) What number are we dividing by?(4) How can you tell? (4 is the size of the jump) So, what is the answer to 20 ÷ 4? (5) How can you tell from the picture? (the number of arrows)    We also discovered that skip counting can be performed by  keeping track of the number of times you skip count, using fingers. For example when s...

Week of May 20th

This week and last, we  revisited  our unit on Data analysis . We  spent time reviewing how to read and interpret information presented  in the form of  pictographs, bar graphs,  line graphs, and line plots . We  learned how to analyze the data presented in the graphs to solve one- and two-step word problems . We  discovered how to use multiplication skills to find the numbers represented on these scaled graphs . As  a class, we collected data about a topic that interested us and created our bar graphs . In  the following week, we will compare all four types of graphs and solve story word problems with the information on the charts.  Our fraction unit is also coming to a close this week. In our unit, we started with paper folding . We  began learning what a unit fraction is and learned the denominator in a fraction is the number of equal parts in the whole  and  the numerator is the number of shaded or selec...

Hurray!! Run and Scream!

The students were so enjoying this game called- Run and Scream as we celebrated National Indigenous People's Day. This is a fun example of a traditional indigenous game that was played to see who has the best stamina. In this game the c hildren would line up, take a big breath, and start running fast while screaming until they ran out of breath . The spot where they had to draw their next breath was marked. With each turn, they tried to better their own distance and pass the marks of others.  They had such a kick out of it that they have asked me several times to post the short video on our blog!!!  Have a great summer everyone:) and thank you for all of your support this year. We had a fantastic time!!! Kindest regards, Sabine Harris
