5 steps to teach concepts ... in math

Last year, I shared a blog post with friends and colleagues on Facebook entitled "Are You Doing It Wrong? How to Introduce Telling Time" by Cindy Lee of Ainslee Labs (which has since been reposted here: Avoid the biggest mistake teachers make when teaching time ).

It caught the attention of my second grade colleagues and now together, we're trying to figure out how to put Ms. Lee's ideas into practice with students.

Traditionally, students are introduced to telling time by first learning time to the hour. Next, students learn to tell time to the half hour, then to the quarter hour, then to the nearest five minutes and finally to the exact minute.

Ms. Lee has experience that shows this way is confusing to kids (I've had that same experience!). We first teach kids to look wherever the short hand is pointing to to read the hour. But soon thereafter, this understanding becomes a misconception.

To address this confusion, Ms. Lee suggests using a clock graphic colorfully divided into twelfths, teaching the kids that each hour has an area or space that belongs to them.

Below, I've detailed how I used my five-step concept-based lesson framework to introduce this idea to the students.

1. Start with a concept
.

Before the lesson, I decided on three related objectives to make sure that my lesson was three-dimensional (to learn more about 3D curriculum and instruction see anything by Lynn Erickson).

Concept: The students will understand that you can't achieve your goal if you use the right tool the wrong way.

Knowledge: The students will know that the hour has an area or space that belongs to them on the clock.

Skill: The students will be able to read the hour on a clock, regardless of how many minutes have passed.

Although I was specifically concerned with students gaining mathematical knowledge and skill during this lesson, I was equally interested in them learning the timeless, abstract, universal and transferable idea that even if you're using the right tool, you need to use it the right away to be able to reach your goals. Striking a balance between teaching and learning knowledge, skill and concept objectives is paramount, in concept-based teaching.

2. Pick a specific, concrete example of a person, place, situation, or thing that illustrates that concept & 3. Create an opportunity for students to explore that concrete example.

To introduce students to the concept of using the right tool the right way, I brought in a tool box, a hammer, a small board and my lanyard.


I told them I had a goal of making a lanyard hanger so that it wouldn't get tangled on my shelf at home. We first chatted about the right tool I'd need out of my toolbox. When we decided that a hammer was indeed the right tool, I tried to hammer in the nail with the end of the hammer. When that didn't work, a student suggested I use the top of the hammer. When that didn't work, someone suggested I used the circle part of the top.

As the nail went into the board, so too did the idea into the kids' brains that you need the right tool used the right way to get the job done!

Then I introduced them to another tool - a clock.

"When we use a clock as our tool, what is our goal?" I asked.

As one girl offered (and all the second graders agreed), we use clocks to read the time.

So, I asked the students to write on their whiteboards what the time was on each of the following clocks:




All the students were able to accurately tell me the time. We all agreed that to read the time on those clocks, you just needed to look where the hour-hand was pointing.

"Okay," I said, "now tell me what time it is."



We counted together that 55 minutes had passed and they all had to read the hour by themselves. Just like clockwork (pun completely intended) all but 1 or 2 students said it was 2:55.


Then, we had a conversation about how we had been using the right tool to tell the time, but we were using it in the wrong way.

Next, I showed them the clock face with the partitioned hours (thanks again to Ainslee Labs for the free clock face. Want to pay for her whole telling time kit?).


We used this clock face to practice telling the time with various times. Over and over again, the students had no trouble identifying the correct hour, even when the hour hand wasn't pointing directly to a particular number. Eventually I removed the gray numbers inside the clock and 100% of the students were
able to read the hour on a clock, regardless of how many minutes have passed because they knew that the hour has an area or space that belongs to them on the clock.

4. Check for understanding by having them write a concept statement. 

(This step is very similar to the thinking routine Headlines found in Making Thinking Visible by Ritchhart, Church, and Morrison, p. 111)

Since I was confident that the students had reached the knowledge and skill objectives of the lesson, I asked, "What did you learn today about how you should use a tool to achieve your goal?".


I gave the students a chance to write down their individual responses on their whiteboards and then one-by-one we shared until everyone's ideas were represented in our statement. Below is the sequence of revisions that our conceptual statement when through. My prompts are highlighted in yellow.

"What do you have to remember about tools when trying to achieve a goal?" First child responds:


"Does anyone want to add anything?" Second child adds:




"Does anyone want to add anything?" Third child adds:



 "Is this true just when we're telling time?" Fourth child adds:



"Who needs to do all of this?" Fifth child responds:



"That doesn't sound right." Sixth child corrects: 



The students were comfortable that their conceptual statement encapsulated all the learning they had done up until that point, so we ended the lesson there.


Often times when crafting conceptual statements (sometimes called generalizations, central ideas, or enduring understandings) we create hard-to-understand statements that don't sound like how we normally talk. Concept statements should be written in language that is easy to understand to all who read it. One way to do this is let the students craft the statement, as we did together in this lesson.

5. Reflect on their thinking and decide next steps.

Moving forward, I would want these students to continue to practice reading the hour using this partitioned clock. Eventually, I would want them to independently be able to read the hours and the minutes first with the partitions and then after slowly taking away that support.

Conceptually, I would want to explore other tools and discuss the correct way to use them and contrast that with the wrong way to use them. This conversation would fit in wonderfully with any beginning-of-the-year guided discoveries that students experience as they are exploring the learning tools of the classroom.

After reading how I used a clock lesson to teach a timeless, abstract, universal and transferable concept to second graders, how do you teach these BIG IDEAS to your students?

Teaching 21st Century Skills with Minecraft

In an attempt to help students who struggle in the areas of literacy and math, our school hosts Learning Academy, a before-school academic support class where students are able to practice and refine skills taught during the school day.

Students are invited to attend Learning Academy when they show they have a deficit in literacy and/or math skills, but it important to remember that these students - nay, all students - also require time and opportunities to develop thinking and communication skills, some of which have collectively become known as 21st Century Skills or the 4Cs: communication, collaboration, critical thinking and creativity.

To foster and support the development of these 21st Century Skills, I invited some of the Learning Academy participants to take part in a @MinecraftEdu class after being introduced to MinecraftEdu at a workshop presented by Alan November (@globalearner). MinecraftEdu is a "school-ready remix of the original smash hit game Minecraft." It builds on the excitement and engagement generated by the game-version of Minecraft to give students an environment in which they can develop and refine various academic and social skills.

Students worked together in worlds downloaded from the MinecraftEdu World Library that other users had created. We worked in the following worlds: Tutorial WorldMultiplying Decimal Numbers, and The Island. In these challenging worlds, students worked on mathematical skills such as understanding coordinate systems, multiplying decimals and long division while exploring, hunting and navigating through adventurous worlds full of obstacles and pitfalls.

After working for several weeks in those worlds, I created a (very simple) world of my own, where I gave students tasks that would allow them to continue to practice mathematical concepts while also giving them the chance to create and build. Below, is a short video showing the students' work on one particular mathematical task I had set up in this world.


Now that this first group of kids has been with me for several months, it is time for the students to move on and a new group to start learning with MinecraftEdu. The week before I said goodbye to this first group of students, I asked them if they could write up a reflection of what they learned, how they learned it and why they learned it. Below are their reflections. 






After reading about how I used MinecraftEdu to help students develop skills of communication, creativity, and creative & critical problem-solving how do you help your students develop these skills in your classroom?
