Paper cup (opaque)
Counters (beans, cotton balls, etc.)
Math Journal
Step-by-Step Guided Lesson
Step 1: Start Video
(Tips: Interact with the video by pausing, to ask questions or discuss information viewed with student.)
Step 2: Teach Lesson
Start the video in Step 1. Once the student has completed the video, use your whiteboard and create Math Mountains.
Have the student solve each problem until they have a firm understanding.
Then read How Many, How Many, How Many
. This book will help the student think about numbers. While you are reading
the book, stop and draw attention to the illustrations. Have the student create addition and subtraction sentences that go
along with the pictures.
Now it is time to play a simple game, How Many is in the Cave? This game works best in pairs.
1. Give each student one cup.
2. Place a specific number of counters in the middle of the two students. Tell the student how many counters they
have to start.
3. While one student covers his/her eyes, the other student takes some of the counters and places them in the
“cave” (under their cup).
4. The student who was covering his/her eyes, uncovers their eyes and tries to guess the number of counters in
the cave.
5. The student can determine this because they know the number they started with and they can see the number
that is not in the cave. Encourage the student to count the remaining counters and use subtraction to solve the
6. Players switch places and the game continues.
7. The game ends once all the counters have been used or after a predetermined time.
Have the students write each number sentences they solve in their math journal.
