Welcome Back!
Come on in and have a seat. We will begin with an
activator in a moment. Please take out your article
that was for homework.
Activate your Minds!Spiney and Other Creatures
I have invented a Pattern Block creature named Spiney. Spiney grows very fast and in a predictable way.
Day 1 Day 2
What will Day 3 look like?
You try to make a creature!(Taken from Super Source Pattern Blocks 3-
4)
Article Club Conversation
Using what you read last night, discuss with your group: Important applications that arose in the
article that directly impact your way of teaching the topic
Did this make you think about changing the way you have taught the topic in the past?
Any other interesting things that arose.
Using other Manipulatives for Fraction Problem Solving
LEGOS! Choose any two lego blocks from the
bag. Write as many problems involving
fractions as you can using the relationship between the two blocks.

How typical are the results for this study?
What implications does this have on our classroom?
Take 5 minutes to talk in your group and then share out.
Adding Fractions
The bar above represents a relay race that 3 students will participate in. Write an equation to represent how much each participant ran.
How much of the race did the first two runners complete?
Adding Fractions
The bar above represents a relay race that 3 students will participate in. Each mark is where you could pass the baton off. All students do not have to run the same amount. What are some possibilities that each runner could run in order to complete the race.

Let’s Regroup
Everyone stand up! When the music comes on circulate around the room.
When the music stops, stop and form a group of 5 people.
You will then create the form that is yelled out!
Modeling Addition of Fractions
Let’s look at several models to add fractions Fraction Bars Fraction Circles Counters (TSCM) Pattern Blocks
Fraction Bars
Place your Bars
in the
communicator
Fraction Bars to Go!
Fraction Circles
From the concrete to the abstract
Have students write the original problem.
Color the sections Trade in the sections to make
equivalent parts Rewrite the problem with the new
sections. Continue for each problem and have
students come up with a rule.
Understanding FractionsAddition of Fractions
You will need to use the pattern blocks to explore and discover.
Pattern Blocks
Try more with Pattern Blocks
¼ + 1/6 =
What did you trade in?
Rewrite with the trade in values?
What would you do if you did not have pattern blocks?
Test Yourself
Estimate and then find your sum.
Use any of the strategies you have practiced.
Try a Ruler (3.MD.4, 4.MD.4) Using a ruler as a visual can help
with adding and subtracting fractions.
May be difficult for ELL students who are not familiar with inches, so you may need to review with how the inch is partitioned and possibly adding labels for fourths.
¾ + ½ = 2 ½ - 1 ¼ =

Common Core State Standards
Let’s take about 5 minutes to look at where our next topic fits in the Common Core State Standards.
Topic: Addition and Subtraction of Decimals 5.NBT.7
If a flat equals one whole, what is the value of:
a long?a block?a cube?
How would you represent .38 ?
What common misconceptions do students have when comparing decimal numbers?
Compare 1.2 and 1.23
Compare 1.5 and 1.46
Compare .7 and .24
Decimal Comparison ….. 4.NF.7
Representing numbers using base ten blocks
Video: How might thisstudent havecompared them differently with base 10Blocks?
Adding/Subtracting Decimals
Let’s Add Decimals using BASE TEN Blocks
We will use the virtual manipulative to model for us.
Use your mat to begin the process yourself.

Adding/Subtracting Decimals
Use what you know …… Add the following using your mat and
the BASE TEN blocks. 4.2 + 3.9
6.4 + 3.7
9.82 – 6.59

Common Core State Standards
Let’s take about 5 minutes to look at where our next topic fits in the Common Core State Standards.
Topic: Factors of Numbers 3.OA.B.6 and 4.OA.B.4
Factors of 24
Make as many rectangles as you can using all 24 squares! Record your models on graph paper and complete the table with the dimensions of your rectangles.
The Product Game
First person places a marker on one number at the bottom.
Second person places a second marker on the same (or a different number) and “earns” the product of the two numbers.
First person can move only one marker and “earns” the product.
Keep playing until 4 in a row!
The Factor Game
Preview… We will be playing later in the lab!
Factor Lattices
Examine the Factor Lattices for the numbers 1-13…what similarities, differences, and patterns do you notice?
When you think you “have it” try creating your own factor lattices for numbers 14-29

Homework
Read the article handed out yesterday about the Standards for Math Practice.
Highlight two things of interest and one thing that surprised you or maybe reinforced what you already do.
Daily Reflection
Take the last 10-15 minutes to reflect on today by filling in the daily reflection sheet
You may also want to go back to your strategy/activity sheet to capture any notes you may have not throughout today.
