Pre-lesson Prep

Like all lessons on Eddy, this lesson follows a certain approach. If this is your first time implementing an Eddy lesson, check out our lesson approach for more information.

Prepare necessary logistics in advance.
- Printouts of Lego worksheets - one per group.
- Printouts of number operations worksheet - one per group
Prepare necessary technology/hardware in advance
- Devices (tablets/laptops/Chromebooks/computers) - one per team
- A stable wifi connection.
- Access to https://www.mecabricks.com/ on each device.

What can I do if I allocate more than three students per group?

In the event of more than three students per group, guide students on ways to be equal and make time within the group to ensure everyone gets their share of hands-on learning. You can also assign the responsibility of monitoring equal making time and an opportunity to voice opinions to one team member.

How does creating a Lego tower lead to durable learning?

Lego construction excites learners and gives them a hands-on into the world of mathematics, leading to durable and fun learning.

Slide	Activity
2	To conduct this activity, begin by sharing the learning objectives for the day with learners.
3-5	You can walk learners through some basic number operations and refresh their memory about the same.
6	Jenga Tower Arithematic: To conduct this activity, print the number operations worksheet and cut out each problem sum to be put on Jenga bricks as labels. You can watch this video tutorial to see how Jenga could be utilized in the classroom. Based on the number of groups in your classroom, keep Jenga bricks stacked as towers ready. Ensure that the problem label faces the top and the answer label faces the ground, such that when a block is pulled out, the problem is visible to the learners first.
7	Introduce learners to the task. Share that two groups would compete over a game of Jenga. This game of Jenga would be a little different from the usual games of Jenga. Each Jenga block has a mathematical problem written on top. A team must answer the problem correctly if they pull a block out. If the answers are correct, they can keep the Jenga block with them. If it is incorrect, they must put it back safely in the Jenga Tower. When the tower falls, the team with more blocks wins the game. Guide two teams to sit facing one another with the Jenga tower in between. The rules for the game, of which the learners are to be informed, are: From any level of the tower, proceed one block on a turn (except the one below an incomplete top level) To finish it, if you’ve answered it incorrectly, place it on the highest level possible. In case if you’ve answered correctly, you will keep the block to yourself. Players can only use one hand at a time. To locate a loose block, players can tap a block. Replace any moved but unplayed blocks unless doing so will cause the tower to collapse. The turn is over whenever the following player touches the tower or ten seconds have passed. Once the timer starts, teams will begin to compete. (Source: https://jenga.com/about.php)
	NOTE: As a less logistics-intensive alternative to Arithematic Jenga, teachers may check out these alternative activities.

For beginners or students who may struggle with the concept of shapes, you may choose to:

Use basic addition and subtraction problems on the Jenga blocks by modifying the number operations template for Jenga. Allow the teams to discuss the answer before responding. Use a smaller Jenga tower with fewer blocks to make it easier to play.

For intermediate learners, you may choose to:

Use a mix of addition, subtraction, multiplication, and division problems on the Jenga blocks. Limit the time the team has to answer the problem to increase the difficulty level. Use a standard Jenga tower with more blocks.

For advanced learners, you may choose to:

Use more complex problems involving fractions, decimals, and percentages on the Jenga blocks. Limit the time the team has to answer the problem, and do not allow them to discuss the answer. Use a standard Jenga tower with more blocks.

Slide	Activity
8	In this lesson section, learners would solve a number operations worksheet and receive instructions on creating a mystery monument upon solving it. Begin by asking, “Have you ever created something with lego?” Wait for responses. Encourage learners to share what they have created with lego. Share that today we would solve math problems to create a mystery tower. Upon correctly solving a math problem on the worksheet, learners would get to know the number of lego bricks to be used in every step of the mystery monument creation.
9-15	Introduce learners to the tool with the help of some guided practice on slides 10-14. Alot 40 minutes of time for learners to freely explore the tool and gain familiarity with the same. Hand out the number operation worksheets to the learners. Share that we would use Mecabricks, an online platform to create things using virtual Lego bricks for mystery monument creation. Open the floor for questions.
13	Apprise learners of the time limit for solving the worksheet and creating the mystery monument, which is 45 minutes.

For beginners or students who may struggle with the concept

Provide extra time for learners to complete the worksheet or build the mystery monument. Simplify the instructions or break the activity into smaller steps. Use manipulatives, such as actual Lego bricks or objects, to help learners visualize the number operations.

For advanced learners:

Once done with the challenge, you may provide learners with the task of adding additional bricks to the creation and further beautifying it, with the constraint that each brick costs a particular amount. They must create it all within a specified budget. You may also choose to provide learners with the opportunity of helping teams still figuring out the task. This would strengthen their learning and allow them to solidify what they’ve learned by explaining the concept to their peers.

Slide

Activity

14

This is the last section of the Lesson, where learners would get the opportunity to reflect on their activity process by sharing three things via a “Rose-thorn-bud” activity. A mindful design-thinking exercise called "Rose, Bud, Thorn" asks participants to reflect on their day's highs and lows and to express their emotions. Learners would share their reflections on the activity by answering the following prompts.:

One accomplishment that makes you proud
What is one thing that excites you?
What is one area where you need more help?

Note: Educators may choose to display the template titled “Class reflection” on the screen or take printouts of the template and distribute it amongst learners to fill up their reflections.

Learning Outcome	Emerging	Developing	Proficient
Solve number operations.	The learner can solve some of the mathematical operations correctly.	The learner can solve most of the number operations correctly.	The learner can solve all of the number operations with accuracy and speed.
3 D Lego tower creation.	Learner faces difficulty in neatly stacking the Legos and navigating the interface.	The learner can create a neat Lego tower, but it consumes time.	The learner can accurately make the tower utilizing the minimum time possible.
