Welcome to Mr. Baker's Math and Science Home Page
Have an excellent Winter Break everyone. We will get back to our learning in the New Year. Enjoy a well deserved break and be ready for all new Adventures in 2019.

Students have started learning how regrouping in subtraction occurs and why we need to ensure we are regrouping from the larger place values. We continue to use number lines to help students understand we are finding the difference between two numbers and we have also supplemented the traditional method to support their progress. See image below for example: For students to reach a in-depth or thorough understanding for most computation processes it takes time and practice. We get lots of both at school, however supports at home would further increase the speed and comfort with this work. This website can create problems for free.
math practice Please check the previous post for their science study guide for Monday's final assessment. 4D and 4C will be having a final Light and Shadow quiz on Monday. Here are a collection of questions to help study. Students NEED to include scientific vocabulary, definitions, diagrams and explanations to earn full marks for each question. The final test will be 4 problems on various concepts we have learned.
Students started subtracting numbers this week. We learned how subtraction is connected to the idea of difference between numbers. Difference is the word that describes the answer to a subtraction question and it can be represented multiple ways. This week students worked on finding the difference using a number line. This strategies has been used before for students to see the visual differences between two numbers. An example is below. Students will need to continue their practice with subtraction and a great way to support is through quick math games. Skip counting backwards by 2, 5, 10, 20, 100 and 1000 from any starting number is very important. Also matching pairs of numbers that add to 10, 20, 100 are also important in our subtraction work. Example: 10 2+8=10 1+9=10 5+5=10 20 12+8=20 15+5=20 4+16=20 100 90+10 80+20 55+45 1000 400+600 200+800 900+100 Here are a couple links to support this work https://www.mathplayground.com/number_bonds_40.html https://www.mathplayground.com/logic_sum_points.html https://www.mathplayground.com/number_bonds_II.html https://www.mathplayground.com/number_bonds_30.html In science students were extremely focused on getting their Mobile Escape Room operational for your tour. They worked diligently in their groups to create challenging puzzles for you to solve. During this work, students completed reflections about how they did in their groups and on their tasks. Students were assessed on the result statements of the report cards. These are not marked on a 1-4 level. The marking format is posted below. The marks were given through classroom observations and the students’ reflections. Supporting their work in the Mobile Escape Room, students continued to learn about light sources, reflections and technology that enhances sight or light.
Science Challenge*** -Document 4 different light sources that you see outside our school make sure you know where the energy is coming from and what direction the light is traveling -Document 4 different reflections that you see. Where did the light come from? How many reflections does it have? What type of object is reflecting the light? -Do you see any technologies in your house that enhance light or sight? |
