๐ Understanding Fact Fluency for Sums of 1 and 2
This lesson plan focuses on developing fact fluency for sums of 1 and 2 in kindergarten students. Fact fluency means students can quickly and accurately recall basic addition facts without relying on counting strategies.
๐ฏ Objectives
- โ Students will be able to quickly recall addition facts for sums of 1 and 2.
- ๐ค Students will be able to represent addition with objects, fingers, and drawings.
- ๐ฃ๏ธ Students will be able to explain their reasoning when solving addition problems.
๐งฐ Materials
- ๐๏ธ Fingers (the best tool!)
- ๐งธ Small manipulatives (e.g., blocks, counters, toys)
- โ๏ธ Whiteboard or chart paper
- ๐๏ธ Markers or crayons
- ๐ Worksheet with addition problems (sums of 1 and 2)
Warm-up (5 minutes)
- ๐ฃ๏ธ Counting Warm-Up: Start by counting to 10 as a class. Then, count backwards from 10 to 1. This reinforces number sense.
- ๐๏ธ Finger Flash: Show a number of fingers (1 or 2) and have students quickly say the number. Repeat several times.
Main Instruction (20 minutes)
- Introduction to Addition (5 minutes)
- โ Explain that addition means putting things together. Use simple language and visuals.
Example: "If you have one apple ๐ and I give you one more apple ๐, how many apples do you have?"
- ๐ค Model using fingers to represent addition. Show 1 finger + 1 finger = 2 fingers.
- Addition with Manipulatives (10 minutes)
- ๐งธ Give each student a small set of manipulatives (e.g., blocks).
- โ Present addition problems and have students use the manipulatives to solve them.
Example: "Put 1 block on your desk. Now put 2 more blocks on your desk. How many blocks are there in total?"
- โ๏ธ Encourage students to draw pictures to represent the addition problems.
- Guided Practice (5 minutes)
- โ Write addition problems on the whiteboard (e.g., 1 + 1, 1 + 0, 2 + 0, 2 + 1, 0 + 1, 0 + 2).
- ๐ฃ๏ธ Call on students to solve the problems and explain their reasoning.
Assessment (5 minutes)
- ๐ Give each student a worksheet with simple addition problems (sums of 1 and 2).
- ๐๏ธ Have students solve the problems independently using fingers, manipulatives, or drawings.
- โ
Collect the worksheets and review student answers to assess their understanding.
โ Example Problems for the Worksheet
- ๐ 1 + 1 = ?
- โญ 2 + 0 = ?
- ๐ 0 + 1 = ?
- ๐ณ 1 + 0 = ?
- โฝ 2 + 1 = ?
๐ก Differentiation
- Support: Provide one-on-one support to students who are struggling. Use manipulatives extensively and break down the problems into smaller steps.
- Challenge: Give students more complex addition problems with sums up to 5 or introduce simple word problems.
