Bug Addition to Ten
Students will be able to use objects to add numbers up to ten.
- Sit with your students in a circle.
- Put ten plastic bugs in a pile in front of you.
- Ask your students to guess how many bugs there are.
- Ask your students to think of a way to make the bugs easy to count.
- Arrange the bugs in an orderly line.
- Count the bugs out loud with your students.
- Tell your students that they will be using bugs to solve addition problems.
Explicit Instruction/Teacher modeling(15 minutes)
- Quickly pass out 10 plastic bugs to each student.
- Tell your students to each put five bugs in a line in front of them.
- Ask your students how many bugs they would have to add to make six.
- Tell your students to add one bug to the line.
- Write 5 + 1 = 6On the board.
- Now, tell your students to put three bugs in a line.
- Ask your students how many bugs they would have to add to make five.
- Tell your students to add two bugs to the line.
- Write 3 + 2 = 5On the board.
- Continue this process with the following: (4 + 3 = 7), (6 + 2 = 8), (3 + 7 = 10), and (9 + 1 = 10).
- Display the Count Bugs on the Rug online game on the interactive whiteboard (see related media).
- Allow every student to have a turn putting bugs on the rug.
Guided practise(15 minutes)
- Keep your students in the circle.
- Ask two students to help you demonstrate how to play the Bug Safari game.
- Tell your students that when you go on a Safari, you explore and collect things.
- Show the game's Number-colour chart.
- Explain that each number stands for a bug in the same colour on the chart.
- Read the directions to your students and then play three or four turns with your student volunteers.
- Ask your students to raise their hands with questions about the game.
- Put your students into groups of three or four.
- Hand out game supplies for each group.
- Tell them to find a place in the room where they can play.
Independent working time(10 minutes)
- Call your students back to the circle.
- Show them the Bug Addition worksheets.
- Explain how to complete the worksheets.
- Hand out the first worksheet and dismiss your students to work at their desks.
- Tell your students to raise their hands when they are ready for the second sheet.
- Observe and support your students as they work.
- Bring the second sheet to them as they finish the first.
- Make sure you check the first sheet for accuracy before allowing them to proceed to the second sheet.
- Allow struggling students to use number lines or manipulatives to help them solve the maths problems.
- Above level students should use 15 counters to compose and write sums over 10.
- During Guided practise, look for students who are taking turns, following directions, and remaining on-task.
- During Independent Working Time, look for students who are following directions and focusing on their own work.
- Your students should be able to trace the numbers on the lines and use the bug illustrations to answer the maths problems.
Review and closing(5 minutes)
- Ask your students to name some ways to make eight, nine, and ten.
- Write their examples on the board.
- Ask your students to name other objects they could use to solve addition problems.
