Scavenger Hunt Addition
- Students will be able to use their own strategies to solve basic addition problems and explain, in their own words, how they got the answers.
The adjustment to the whole group lesson is a modification to differentiate for children who are English learners.
- Invite the students to come together into a group.
- Ask the students if they have ever done a scavenger hunt. Call on a few students to explain scavenger hunts that they have done in the past.
- Explain to students that today they will be partaking in a maths scavenger hunt!
- Ask students to look around the room to observe the colorful paper hanging on the walls and seats. Tell them that these sheets are labelled with a letter from A-T and have a maths problem on each of them to solve.
Explicit Instruction/Teacher modeling(10 minutes)
- Write five addition problems on the whiteboard.
- Explicitly model how to solve the problems using strategies already discussed in class.
Guided practise(10 minutes)
- Take out the recording sheet. Show the students the sheet and point out that the recording sheet has a table with letters A-T written on it.
- Explain to the students that they will search for the colorful sheets with addition problems hidden around the room.
- Model searching the room for an addition problem and recording the problem in the box that matches the letter on the problem.
- Explain to the students that they do not have to start at the letter A, they may start at whichever problem they see first!
- Model having walking feet and quiet mouths during this activity. Remind students that they are to keep their hands to themselves and focus on solving the addition problems during the activity.
Independent working time(25 minutes)
- Pass out the recording sheets to students.
- Tell the students that they will have 25 minutes to solve as many addition problems as they can.
- Students who need to be challenged can work with a partner and compete to see who can finish the problems in the least amount of time. Next, ask them to compare their answers and if they notice that they do not have the same answer, ask them to solve the problem again and compare answers again. If the students finish with ten or more minutes left, let them complete the Sky High Addition worksheet.
- Students who need a little extra support can be paired with a peer who is more fluent at solving addition problems.
- Hang 10 sheets of a different colour around the room. Write down basic addition problems up to 10 such as 1 + 1, 3 + 2, 4 + 4, etc. Use shapes such as circles, stars, or squares to represent each digit and draw them under the numbers. Students can use the strategy of counting the pictures to solve the problem. You may also offer the students blocks or other tangible items to help the student solve the problem.
- Rotate around the classroom as students are completing the scavenger hunt to help struggling students. Make note of students who are having a hard time solving the problems.
- After the conclusion of the lesson, display an answer key on the board and ask students to correct their papers using a red pen.
Review and closing(5 minutes)
- Invite students to come back together as a whole group.
- Ask students to use the 3-2-1 rating scale to rate the scavenger hunt they just played. 3: I enjoyed the game and I thought it helped me with the concept. 2: the game was okay, and it did help me to review solving basic addition problems. 1: I didn’t like the game and I didn’t feel it was beneficial to my learning.
- Make note of students' comments.
- Ask students to share the most challenging problem they encountered and invite a student or two to come up and show the strategies used to solve the problem.
