our Instruction Identify the 3 major shifts in math education

Last week, I was at a restaurant with a group of friends. The bill came and this is what was

said…

“I’m not good at math, have Drew

figure it out.”

Out to lunch…

Next time we go…“I’m not good reading, can you read this

to me?”

Same Reaction?

Illiteracy Innumeracy

Why is it socially acceptable to be

innumerate?

Innumeracy21% of Americans possess numeracy skills at the lowest level . . . [which] means that

people cannot . . . work out the change from $2 when buying

goods worth $1.58.

Making Banners

You have 9 yards of fabric.You need 2 of a yard to make a banner.How many banners could you make?

We have number lines, graph

paper, and blank paper available.

Approaches? Now let’s change the numbers…

Making Banners

You have 9/4 yards of fabric.You need 1/2 of a yard to make a banner.How many banners could you make?Solve 2 ways– number line/picture AND then computation

We have number lines, graph

paper, and blank paper available.

Under every other chair there is a solution to this problem. With a partner, show how how

a student might arrive at this solution.

How are your solutions the same?How are they different?

Making Banners

Listen as groups share what they noticed4 ½ 4 2 9/8

A Lesson in the “old” DaysWhat did math class look like when you were a student?

First, invert the 1/2 so you now have 9/4 x 2/1

Next, multiply 9x2 to get 18, then 4x1 to get 4.Now we need to reduce so you take 18 divided by 4 to get 4 r 2 or 4 2/4 that needs to then be reduced to 4 1/2

4 ½ 4 2 9/8

Which answer does method this lead to?

“Don’t Ask Why, Just Invert and Multiply!”

During and after reading a selected text, we ask…

“What do you notice in the text?”

“Do you agree with the characters decision

to…/why?”

After solving a math problem, we ask…

“Did you get the right answer?”

Numbers….9 divided by 2???

How did changing the numbers influence the “difficulty” of the task?

9/4 divided by 1/2

Procedures = Understanding

17- 6

10- 6

How did changing the numbers influence the “difficulty” of the task?

Procedures = Understanding

17- 6

By place value…start at the right…Ones column: 7- 6 = 1. Tens column: Bring down the 1.I have a 1 in both places. Answer is 11.

Procedures = Understanding

10- 6

By place value…start at the right…Ones column: I can’t do 0 minus 6.

Go next door… change the 1 to a 0 in the tens

Change the 0 to a 10 in the ones.Ones: 10 – 6 = 4Tens: 0 – 0 = 0.I have 0 tens and 4 ones. My answer is 4.

Do they understand?

The Three Shifts in Mathematics

Focus specificity and concentration on fewer “big ideas”

Coherence: Think across grades and link to major topics within grades

Rigor: Require conceptual understanding, fluency, and application

Shift One: Focus strongly where the Standards focus

Significantly narrow the scope of content and deepen how time and energy is spent in the math classroom

Focus deeply only on what is emphasized in the standards, so that students gain strong foundations

It starts with Focus

The current U.S. curriculum is ‘a mile wide and an inch deep.’

Focus is necessary in order to achieve the rigor set forth in the standards

The following graphs refer to mathematics instructionWith a partner, predict what these represent

Walk and Trade

Shift Two: Coherence Carefully connect the learning within and across

grades so that students can build new understanding onto foundations built in previous years.

Begin to count on solid conceptual understanding of core content and build on it. Each standard is not a new set of events, but an extension of previous learning.

Coherence Within GradeLook within your grade and find where

important concepts are connected across domains.

Shift Three: Rigor

The CCSSM require a balance of: Solid conceptual understanding Procedural skill and fluency Application of skills in problem solving situations

This requires balanced intensity in time, activities, and resources in pursuit of all three

An Experience with Students

The following slides are from DPI.

The Task

What would that look like…

With our students?

Step 1: Introduce/Review Standards for Mathematical Practice # 4 and #5

Date:

Briefly describe how you will introduce/review Standards for Mathematical Practice # 4 and #5

Step 2: Apply Standards for Mathematical Practice # 4 and #5 to a math lesson.Select a lesson that provides students the opportunity to choose appropriate tools strategically and model with mathematics.

Briefly describe lesson chosen:

Toward the end of the lesson, ask students to illustrate how they used mathematical practice #4 OR #5 in their work today.

Step 3: Bring illustrations to math planning.As a team, choose 2 illustrations (one that shows a solid understanding and one that shows minimal understanding). Send illustrations in to Amy and Marilyn (use envelope provided).
