– Develop persistence and be patient – it takes time to teach students
how to think, reason, explain, use different strategies.
– Ask questions: How did you do that? Can you explain that? Can you
try another way? What do we know? What do we have to find out?
Have you done another problem like this one?

haven’t memorized the basic facts?haven’t memorized the basic facts?
• Basic facts are being practiced daily but not drilled and timed.
• Along with being accurate, it is critical that students understand the concepts and develop
number sense. If students don’t know the relationships between numbers, they will not
develop accuracy and efficiency when working with numbers.
• There is no race to see who gets finished fastest. Timed tests develop anxiety not accuracy.
Timed tests will be removed from the PATs (Provincial Achievement Tests) in grades 3 and 6.
• It takes time to learn concepts, and understand relationships between numbers.
• Some students find memorization very difficult, some students find explaining their answers
very difficult. Memorizing without understanding doesn’t last. It must make sense, then they
will remember it. It takes time to find personal strategies that they understand and can use.
The new program recognizes this by having grade K – 9 slowly develop the same concepts.

fewer skills all the time. How will this program address this?fewer skills all the time. How will this program address this?
• It is important that we teach students how to make sense of information and how to work
persistently to solve real life problems.
• In Kindergarten to grade 9, students are taught how to think and reason to understand concepts
and to make sense of mathematical ideas. Students develop personal strategies to solve
problems. Students will be more prepared to handle the more complex and abstract concepts in
junior and senior high.
• As adults, most of the math we use is mental mathematics and estimation. We use math for
shopping, reviewing bank and credit card statements, paying bills, etc. If we need one, a
calculator is always near by. Should we spend 4 years of school drilling students how to do
long division by hand? Students need to understand it, know when to use it, and estimate a
reasonable answer.
• Geometry and measurement are equally important as an adult when following directions, buying
rugs and paint, assembling BBQs, furniture, building decks, doing repairs,etc.
• Data analysis and identifying patterns also important to make sense of data and make valid
interpretations of the huge amount of information we have available today.

• The goal is to prepare our students to:
– Use math confidently to solve problems
– Reason and communicate mathematically
– Appreciate and value mathematics
– Make connections between mathematics and its applications
– Commit themselves to life long learning
– Become mathematically literate adults using mathematics to contribute to
society
• It’s a big goal, but very attainable – with your help. Parents play a huge role in
their child’s education. By encouraging a positive attitude, building persistence,
strategizing in games, discussing with your child real life applications of math
skills, your child will truly succeed.

How can I help him? – Keep a positive attitude, build confidence. It is important that he hears that you believe that he will learn how to do it. – Develop persistence and be patient – it takes time to teach students how to think, reason, explain, use different strategies. – Ask questions: How did you do that? Can you explain that? Can you try another way? What do we know? What do we have to find out? Have you done another problem like this one?

How can anyone do any math if theyBasic facts are not being practiced. How can anyone do any math if they haven’t memorized the basic facts?haven’t memorized the basic facts? • Basic facts are being practiced daily but not drilled and timed. • Along with being accurate, it is critical that students understand the concepts and develop number sense. If students don’t know the relationships between numbers, they will not develop accuracy and efficiency when working with numbers. • There is no race to see who gets finished fastest. Timed tests develop anxiety not accuracy. Timed tests will be removed from the PATs (Provincial Achievement Tests) in grades 3 and 6. • It takes time to learn concepts, and understand relationships between numbers. • Some students find memorization very difficult, some students find explaining their answers very difficult. Memorizing without understanding doesn’t last. It must make sense, then they will remember it. It takes time to find personal strategies that they understand and can use. The new program recognizes this by having grade K – 9 slowly develop the same concepts.

How will this program address this?fewer skills all the time. How will this program address this? • It is important that we teach students how to make sense of information and how to work persistently to solve real life problems. • In Kindergarten to grade 9, students are taught how to think and reason to understand concepts and to make sense of mathematical ideas. Students develop personal strategies to solve problems. Students will be more prepared to handle the more complex and abstract concepts in junior and senior high. • As adults, most of the math we use is mental mathematics and estimation. We use math for shopping, reviewing bank and credit card statements, paying bills, etc. If we need one, a calculator is always near by. Should we spend 4 years of school drilling students how to do long division by hand? Students need to understand it, know when to use it, and estimate a reasonable answer. • Geometry and measurement are equally important as an adult when following directions, buying rugs and paint, assembling BBQs, furniture, building decks, doing repairs,etc. • Data analysis and identifying patterns also important to make sense of data and make valid interpretations of the huge amount of information we have available today.

Parents play a huge role in their child’s education. By encouraging a positive attitude, building persistence, strategizing in games, discussing with your child real life applications of math skills, your child will truly succeed.

Editor's Notes

  • #2 Introduce yourself and welcome everyone. I can see and hear that you are enjoying playing Pig, and as we go through the presentation, you will see how it relates to the new math program. In the next 1 – 1 ½ hours, we are going to learn about the new math program and hopefully have some more fun along the way. Today’s presentation will tell us (read the points as they appear on the screen) what stayed the same, what changed, what I should see in my child’s classroom, how I can help at home, and some frequently asked questions.
  • #7 Less content does not mean that we need less time to teach mathematics. In the past years teachers at all grade levels have been telling us there just isn’t enough time to do the hands-on activities that they would like to do; there are just too many concepts to cover in the amount of time given to teach mathematics. We heard this and in response we have reduced the number of outcomes at each grade.
  • #8 In “Coming to Know Number” you will also find multiplication Two Ways. Multiplying across the top yields 8 (space bar). 3 x 5 = 15 (space bar). Reading down, 4 x 3 = 12 and 2 x 5 = 10. Now, along the bottom we can see that 12 x 10 = 120. Reading down on the right, does 8 x 15 also equal 120? Yes, and all the computations check out. An examination of other Two Ways shows that it becomes more problematic when the numbers given are not in all in the upper left. Numbers presented in this format encourage students to think meaningfully about multiplication and division rather than just following some rule that may not have meaning for them. Number sense is fostered.

  • #14 This page of Two Ways presents challenging multiplication and division of fractions tasks. There are rich opportunities to build fraction knowledge in these activities. The remarkable aspect of this set is that students enjoy and will work on them when they might see a long list of fraction computation exercises. The format makes a difference. Consider the Two Way in the lower right corner. Down 4 is the number x 4 that equals 16. Across 5 is the number x 4/5 that equals 4. 4/5 is the number times 20 that equals 16 Down 25 is the number times 4/5 that equals 20 4/25 is the number x 25 that equals 4 Down (check) 5 x 4/25 = 4/5 This will surely challenge your best students!
  • #15 A person just glancing at the page of Two ways on the previous slide might not realize how much computation is involved. Because of the format, the page is not intimidating. However, there are 54 computations (shown in this slide) required to complete this page!! Show this to persons who might wonder about the value of Two Ways. However, what is most important is the demanding mathematical reasoning required to “solve” the Two Way problems.

  • #57 Let’s start with something we are all familiar with – addition of 2 digit numbers. There were 57 students in Mr. Heuser’s grade 2 class and 48 in Ms. Lyon’s grade 3 class. The two classes were going on a field trip together to the zoo. How many tickets would they need to buy so each student could go to the zoo? Again, we have tried to use PS as a way for students to attach meaning to their mathematics. The digits on the right are labeled “ones”. The digits on the left are labeled “tens”. Start with the ones: 8 + 7 = 15 (This answer may be arrived at because the students know s this fact or they may use the add on strategy to get 15.)

  • #60 Go through the slide point by point. It is sometimes very hard to be positive when you hate math and feel you can’t do it. But it is critical that you pass along the encouragement that he will get it, he can do it. Develop persistence – it is a skill for life.
  • #61 Go through the slide point by point In Japan, basic facts are taught at home only – not in school. School teaches concepts and relationships.
  • #63 When you were playing Pig, and solving the feet problem, you were using math confidently, reasoning and communicating, making connections, learning, and having fun. That is how we know children learn. I am excited about the new program, and am looking forward to seeing students confidently having fun and succeeding in math. Thank you for coming this evening. I hope you have enjoyed it and learned what the new math program is about. If you have any questions please don’t hesitate to ask. Have a good evening and drive safely.
