This week students have been busy refining their addition skills. Students proved they understood how to regroup numbers into the 10 000s using the strategy they feel comfortable with. This week students worked on decoding word problems for clues and then using their adding strategies to solve the problem successfully.
Here is a computation generator that will make endless amounts of questions for you to practice. How big can your numbers get? Does your strategy work for all numbers?
Students have been signed up for Prodigy, which is a free online math program. The students will be exploring this resource the next few weeks and it can also be done at home. They will have a user name and password to log in. It will be a great resource for refining skills.
It can be found at this link:
Next week students will begin subtraction. This will take some time and practice as subtraction is a difficult concept to grasp when regrouping is needed.
This week the students learned the importance of protecting our eyes from the sun’s rays. This will be really important when they go skiing on Tuesday as the sun reflects off of the snow. If they could wear sunglasses or goggles that would be best.
Students also began to explore the scientific method, which is the process scientists use when conducting experiments.
This is a more elaborated version, however we talked about the same process:
Students have been very busy this week as they began to review their strategies for addition. We moved passed our three-digit addition into the Grade four realm of 4 digits. Students are consistently adding up to almost 10, 000. We reviewed two new concepts building off of using base ten. The strategy we practiced for many days looks like:
This strategy works through each place value system starting with:
5 000+ 1 1000=6000
They then find the sum of all these numbers. This strategy is longer than the traditional algorithm, however it saves all the regrouping to the end so they do not get confused.
On Monday the students have a four-question addition check in. They can choose ANY strategy for adding as long as they can show their thinking.
They can get practice from the following links:
Family Dice game dedicated to adding BIG numbers
Students really worked to understand the difference between light sources and reflections of light. Students became quite capable understanding where the sources of light came from and how many reflections were involved.
The moon’s reflection on the lake
-Starts with the sun reflecting off the moon
-The moon reflects the light to the lake
-The lake reflects the light again
Students also had to generate lists of light sources:
Can you name 6 different light sources?
What if we didn’t have electricity how many can be named?
Next week students will be learning more about shadows and the way light travels in our world. Reading these articles will help you further understand the impact light has on our world.
We would like to welcome Ms. Chapman to our classroom. She is a university student from UofL. Ms. Chapman will be spending a month learning right beside us. This week the students were busy learning how to regroup with four digit numbers using base ten blocks. This process is very important as students are beginning to do larger computation questions soon. Base tens are a visual math tool to help students understand the concept of regrouping or (Carrying). Here is a visual:
If you would like to practice the regrouping process this link can help with that:
Students continued to learn about light and shadows in our world. We had a discussion about phases of the moon and how they are created by different shadow angles.
Students can start searching their homes and environments for sources of direct light and also reflections of light. We will be focusing on these areas next week and understanding the differences.
The students spent a good portion of this week reflecting and sharing their science project with their peers. It was wonderful to see the dedication students put into not only finding a problem their were passionate about, but being creative with their designs and materials. The final mark for these projects will include many aspects of the students’ work such as: The design and building process, their write up and logbook, multiple reflections they wrote in class and their presentation to the class. I would like to thank all the students and their families for the support in our Waste in Our World unit. We are now moving into Light and Shadow for our next science topic.
To get a jump-start on Light and Shadow take a look at these links:
In math, students worked diligently to complete their unit on Patterning. They had a work period where students had opportunities to review prior skills and strategies as well as asking questions to peers and the teachers. Students completed a math assessment this week and will be bringing it home next week. We will be spending time now focused on our four computations. Adding and subtracting up to 10 000 will be our first step as well as multiplying and dividing double digits. If you want to get some practice in you can use the following links:
Students also continued to build their understanding mental math strategies. This week we really focused on our ability to count by 50s and 100. We then looked at the relationship of the numbers 99 and 49. This means if we can add 100 to a number we can add 99 just by taking one away! This saves a lot of time regrouping!
Teach someone in your family this strategy
We are working on clearly communicating when problem solving. Remember you need to show each step of your thinking. Here are some problem solving questions to help practice.
Students were extremely lucky to have Ms. Williams join our classroom. She taught an engaging lesson about packaging of everyday products. Students engaged in a lesson dedicated to breaking down the pros and cons of certain packaging materials. This will be one of the final sections for our Waste in the World unit. Next week students need to bring in their science project with completed documentation sheets for Monday. We will be doing a large scale sharing in the class and across the grade. Then, we will be starting Light and Shadow.
Students have been working on finishing their patterning unit. They worked on a multi-stepped problem today that combined quite a few ideas they covered this week. The problem is posted below. Have your child explain the steps and importance to each section of the lesson.
Next week students will be reviewing the concepts on Monday and be working on a unit assignment for Tuesday. Check back to the previous blog links for review of the concepts we covered.
