1. Welcome to curriculum night the ‘Chelsea experience’

2. Eureka Math What is Eureka?
The Eureka Math resource was built around the core principle that students need to know more than just what works when solving a problem – they need to understand why it works.
Why Eureka?
Eureka has received high ratings from educators nationwide and school districts are seeing growth and impressive test scores after just one year of implementation.
Eureka with Growth Mindset
Students with a Growth Mindset aren’t afraid to make mistakes. Brain research shows that mistakes are good and help you to learn more. Kids with a Growth Mindset achieve more.

3. What will Eureka look like in the classroom?
Typically, there are 6 components to each lesson
Fluency – Daily math fact practice which is used to maintain skills, prepare for the current lesson, and/or anticipate skills used in future lessons
Application Problem – Word problem which can lead into the concept development or review a concept from the previous day
Concept Development – Majority of the lesson which teaches a particular skill. Can include a variety of activities (whiteboards, manipulatives, partner work)
Problem Set – Independent practice to apply the skills taught from the concept development. Sometimes students will work on only a few problems
Debrief – Reflection after problem set to review as a whole class a few areas
Exit Ticket – Quick gauge of student understanding of the day’s skill

4. Eureka School/Home Connection
Problem Sets
Problem Sets can come home unfinished and that is okay.
Exit Tickets
Exit Tickets will be coming home frequently and it is encouraged to review the Exit Tickets with your child at home.
Assessments/Rubrics
Assessments can be informal observations, exit tickets, mid module assessments, and end of module assessments. Rubrics will be used to grade and inform you of your child’s progress on the mid module and end of module assessments.

5. Eureka School/Home Connection
Homework
The purpose of daily practice at home is to reinforce skills taught at school. The expectation is that your child will be completing the assigned homework that correlates to what was completed on the Problem Set for that day. Zearn is an additional resource that serves as a great daily practice as well.
Letter/Login
Please refer to your parent letter with your online account login information for greatminds.org. This was sent home the first week of school. You also received an e-blast from the district last Thursday. Students have already received their Zearn login information as well.

6. The Evolution of a Number Bond
Let’s look at this example, which shows one way a 1st Grade child might determine the sum of 8 and 5 using the skills he learned in Kindergarten. The student knows he wants 2 more to put with the 8 to make 10 and he knows he can decompose 5 into 2 and 3. So now he is thinking of 10 + 3, or 13.

7. Let’s move on to 2nd Grade, where students are expected to “add and subtract within 100 using strategies based on place value, properties of operations, and/or the relationship between addition and subtraction”.  Now our student is faced with finding the sum of 37 and 25, which would normally be thought of as a “regrouping” problem.  This student is still looking to make 10s, so she knows she needs 3 more to make 37 into 40.  And notice that she is really still splitting 5, even thought now it’s actually 25.  After splitting, she’s got an easy mental problem in 40 + 22.

8. Let’s move on to fractions
Let’s move on to fractions.  In 4th grade, students must “decompose a fraction into a sum of fractions with the same denominator in more than one way” and “add and subtract mixed numbers with like denominators.” Let’s see how our number bond knowledge can help here. We split the 4/5 into 2/5 and 2/5 to create a whole out of the 3/5, resulting in 1 2/5.  Seems a bit easier than finding an improper fraction and then introducing a totally different procedure for converting it to a mixed number.

9. How about measurement. Elapsed time maybe
How about measurement?  Elapsed time maybe?  Doesn’t this actually mirror what we do when we calculate elapsed time mentally?

10. Or adding and converting measurement units?

11. Now it is your turn to try a Number Bond.
Notice that all of these examples follow the same format for recording the “splitting” process, and that it all starts in Kindergarten!
Now it is your turn to try a Number Bond.  
Johnny started football practice at 2:30 p.m. He practiced for 90 minutes. What time did Johnny finish football practice? Use a number bond to solve.
2: minutes

16. Vertical number line: third grade What’s halfway between 6 hundreds and 7 hundreds?

17. Vertical number line: fourth grade
Round a Four-Digit Number:
Round 214,569 to the nearest thousand.
How many thousands are in 214,569?
One more thousand would be?
What’s halfway between?
Where should I label 214,569?
Which endpoint is it closer to?

18. Vertical number line: fifth grade
Round to Different Place Values
Say the number. Draw a vertical number
line with two endpoints and a midpoint.
Round to the nearest one.
8.735 ≈ _____
Between what two ones is 8.735?
What is the midpoint?
The midpoint is the same as how many tenths?
How many tenths are in 8.735?
Is that more or less than the midpoint?
Show on your number line.
Now it’s your turn. Round 151,283 to the nearest ten thousands.
