Warmup Look at the figure to the right. Which number doesn't belong? There are many reasonable answers. Your job is to explain your choice using logic. Hand In Students handed in their journals. Learn: Worktext pp.38-42 Students learned how to add and subtract fractions. Practice: pp. 43-47 Beginning/Developing: (#5, 6) even letters only, #7-10 Confident: (#5, 6) last 4 letters only, #7-14. |

Popsicle Stick Day Warmup Look at the figure to the right. Which number doesn't belong? There are many reasonable answers. Your job is to explain your choice using logic. Hand In Students handed in their journals. Learn Students learned how to use the multiplication chart to multiply, find multiples, divide, find common factors and equivalent fractions. Review and Practice Students used the remainder of the class to prepare for the term assessment which will be next class. |

Warmup Arrange 10 pennies as shown to the right. Now move 3 pennies so that the triangle is upside down. Hand In Students handed in their journals. Review and Assessment Students asked for assistance with the challenging questions from last day's practice. Individual Quick Review: Multiplying Fractions Learn Students learned how to divide whole numbers with fractions using visual models. Students in Block 1B will do this next class as the blocks were shortened today. Practice Students in both blocks should make sure that they have completed the assigned questions about multiplying fractions. Ms. H will be checking their workbooks next class. Practice for students in 2C only. Complete the exercises on pp. 1 and 3 in the booklet. |

Warmup From the setup to the right, remove 8 matchsticks to leave exactly 2 squares. Hand In Students handed in their journals. Review and Assessment Students were able to ask questions about the quiz material. Then they wrote the quiz about fractions: what are equivalent fractions, how to simplify fractions and how to know whether a fraction is larger than another one. Learn/Review We learned/reviewed how to multiply fractions by fractions using a visual model (diagram). Then 1B reviewed how to cross-cancel when multiplying fractions. Practice Students in 2C should complete the second page of the multiplying fractions handout (both sides). Students in 1B should complete the last two pages, both sides, of the multiplying fractions package for next class. |

Warmup You have 5 small boxes which look exactly the same. The boxes are labelled 1 to 5. One of the boxes is a little heavier than the others. You have a balance with two pans like the image to the left. Each pan can hold all 5 boxes if needed. You do not have a scale to measure weight. How can you figure out which box is the heavy one? What is the fewest number of steps that you would need to find out which one is the heavy box? If you had 9 boxes instead of 5, what would be the fewest number of steps to find the heavy box? Hand In Students handed in their journals. Learn Using prime factorization to find LCM and GCF with a list or a chart. The chart strategy is more appropriate for students who are comfortable with dividing; however, it often saves time so all students should find it helpful. The earned marks are the same regardless of the method the student chooses to use. Assignment-This is due at the beginning of next class and will be used as an assessment. Beginning/Developing: Using Prime Factorization to find the LCM and GCF- odd numbers only GCF and LCM Word Problems-#1 and #2. Confident: GCF and LCM Word Problems-all |

Warmup We continued with the same question as we have been working on for the last two classes. This time, we used the strategy of taking a complex problem and trying to solve a slightly simpler version of the same question. From there, we might be able to see patterns that could be used to solve the original, more complex, problem. Today, students tried to write the numbers 1 to 6 in the circles (see diagram to the left) so that the sum of the 3 numbers that make up each side of the triangle is equal. They were told that there is more than one solution. Many students were able to find at least one solution and describe their strategies. Hand In Students handed in their journals. Review We reviewed the definitions of prime and composite numbers and gave examples of each. We also discussed the fact that other than 2, all prime numbers are odd. However, not all odd numbers are prime numbers. Learn We learned the definition of "factor" and practiced listing the factors of given numbers. We used the rules of divisibility to help us determine which numbers could divide the given number evenly. We also used the strategy of dividing the given number by the smaller factors to find the larger factors. Practice Unfortunately, we did not have much time to practice so we will practice next class. |

Warmup 1. Write the numbers 1 to 9 in the circles (see diagram to the right) so that the sum of the 4 numbers that make up each side of the triangle is equal. The purpose of this exercise is to use your number sense to think about how to arrange the numbers. You might not find a solution but you should be able to get close to one. -The students were overall very engaged so we worked on this for longer than usual. -Because this is quite a challenging puzzle, we will work on it again next class. Learn 2. Unit 0 Checklist: We learned how to use the unit checklists to self-evaluate at the beginning of a unit. This took quite a long time as students are just being introduced to the system. It should be a smoother process as we work through the year. 3. Notebook Organization. 4. We began looking at Divisibility Rules. 2-C was able to work through one teacher-led example. |
