Differentiated Instruction without much work

How can we differentiate instruction without putting more work on our plate?

Teachers do not have time to prepare multiple tasks and lessons to meet the needs of each student in the classroom.  The key is giving an anchor task that all students can enter and knowing how to adjust the task based on our observations.

In this class, students were guided to use “Katell’s” method (aka-left to right strategy) to solve the problem 65 – 12.  Notice how the student recorded their thinking process.

How can we differentiate with one task?

During the guided structure component of the lesson, teachers are observing and questioning students.  This student demonstrates and can explain the left to right strategy.  What comes next for this student? During our planning phase, we need to ask ourselves, “What can I do for the student that already knows the answer”?  Looking at this student’s work, how can we deepen the mathematical understanding?

After listening to the student explain his thinking, the teacher commented, I can understand your verbal explanation, but your written work is confusing to me.  I wonder why I am confused? The teacher then walked away, and the student grappled with the idea of equality.  Differentiation is meeting the student where they are at and extending the learning.

Do not try to create more problems for students to practice.  Plan your task thinking of what mistakes students typically make and how you can help extend the thinking. Use your observations to go deeper and differentiate!

What are other ways you could take the task 65 – 12 and extending the task?  Share your thought below.

Conceptual understanding comes first!

How can we help student refocus on understanding versus just an answer?

Too often when we pose a problem and students shout out an answer.  We need to ask ourselves do students understand the concept or are they obtaining the correct answer by fitting the symbols and numbers into a structure they know?

In this example, the anchor task was to subtract 34 from 87.  The teacher wanted to screen the children first wondering, Do students know what it means to subtract one number from another?  To find out more the teacher posted the following problem, removing the numbers.

Do students have the conceptual understanding or just fit the numbers into a given structure?

Students were asked to set up the expression that could represent the situation.  The student A on the far right was the only student in the class that seemed to understand. When asked to explain his thinking, many observing teachers felt he understood the concept and that he gave us a platform to generate a discussion.

Do students understand the part-whole relationship here?

Following this analysis, the numbers were inserted into the problem.  Subtract 34 from 87.  It was interesting to see student A’s work.  Much to our surprise, Student A who seemed to understand the concept had a hard time transferring that knowledge to another situation.  Notice his equation is not correct but he gets the final answer.

Can student A  transfer knowledge from one setting to the next? Look and listen to help guide students to conceptual understanding.  Looking at answers does not tell us the whole story.

Less is more.  Spend more time on conceptual understanding and listening and watching students versus solving more problems.  The answer does not help assess student reasoning or how we can extend or guide the learning process.

Grade 1 Task

Grade 1 Task- Not enough information

At 2017 Mathodology Fall Institute participants worked on a task from think!Mathematics which required them to use the given shapes to make a composite figure. Figure C posed a problem for many.  Is it possible?  Participants worked and worked and did not find a way to solve the problem with the given shapes.  The teacher allowed the task to move on without closure for a purpose.  When students work to become confident problem solvers we want them stating, “Figure C is not possible with the given shapes.  I would need an additional… to complete this shape.”  We have built perseverance and another way to assess them.  Do they know what to ask?  “I need two more pieces of one shape.”

When we do not provide immediate closure, we allow students to continue to explore.  Many participants emailed after the institute because they would not quit until they figured it out.  Below are a few of the pictures they sent.

Try giving a task where there is not enough information and see how your students handle it.  Will they be confident to state this is not possible, and know what to ask?

Great perseverance by participants who refused to give up?

Grade 2 begining Journal Entry

Journal Entry:  Given a number write four things you know about that number.


How can we use this to help assess where a student is before we even begin a formal lesson?
