Data Workshop Teacher Guide Data Workshop
Teacher Facilitation Guide • Grade 1 Tier 2 Intervention
Standard
1.MD.C.4
Instructional Objective
Students will organize up to three categories of physical objects, represent the data on a graph, and answer questions about totals, category counts, and comparisons (more/less).
Materials Needed
Sorting Mats & Graphing Mats
Manipulatives (buttons, bears, or blocks)
Crayons or Markers
"Data Detective" Worksheet
1 Phase: Concrete (The Sort)
Teacher Action:
Give students a handful of mixed items (e.g., 4 red bears, 6 blue bears, 2 yellow bears). Ask: "How could we organize these so we can see which color has the most?"
Key Questions:
"Which box should this blue bear go in?"
"How many are in the yellow group? Let's touch and count."
"Which group looks the biggest? How can we be sure?"
2 Phase: Pictorial (The Graph)
Teacher Action:
Transition students to the Build & Count Graph Mat . Have them move one object at a time from their sorting mat to the graph grid, starting from the bottom. Then, have them remove the object and draw a circle or square in its place.
Key Questions:
"If we take away this bear, what can we draw so we remember it was there?"
"Looking at our drawing, how many more red bears do we have than yellow?"
3 Phase: Abstract (Interpretation)
Teacher Action:
Use the Data Detective Challenge . Students look at a printed graph and answer written comparison questions without having physical objects to move.
Key Questions:
"How many objects are there in all? How did you find that total?"
"Which category has the fewest?"
Misconception Watch
Gap/Overlap Error
Students may leave gaps or overlap items on the graph mat. Remind them: "One box, one object. Start at the bottom line."
"How Many More" Confusion
Students often state the total of the larger group. Use a physical 1:1 matching strategy to show the difference visually.
Data Sorting and Graphing Mats The Sorting Station
Place your items in the circles below to organize them.
Student Name
Group 1
Label:
Group 2
Label:
Group 3
Label:
First: Sort your objects into the three circles by color, shape, or size.Next: Count how many items are in each circle.
The Graphing Grid
Line up your objects in the columns below.
Graph Mat #1
0 1 2 3 4 5 6 7 8 9 10
Category 1
Category 2
Category 3
First: Move your objects from the Sorting Station to this grid. Start at the bottom.Next: Trace or draw a picture of the object in each box to make your picture graph!

Data Reference
Jump Ropes: 4
Balls: 6
Hula Hoops: 3
Question 1
How many Balls?
6
Question 2
How many Jump Ropes?
4
Question 3 (Comparison)
How many more Balls than Hula Hoops?
3
Calculation: 6 - 3 = 3
Tier 2 Tip: If student answers "6", they are naming the larger group total. Model physical 1:1 matching using cubes to show the "extra" balls.
Question 4 (Comparison)
How many fewer Hula Hoops than Jump Ropes?
1
Calculation: 4 - 3 = 1
The Big Total
How many toys are there in all?
13
Calculation: 4 + 6 + 3 = 13
