Grade Level: 2nd Grade
Concept: Mathematics (Number Sense: Skip Counting)
Objectives: Students will be able to skip count by 5’s and 10’s using their base 10 counting blocks. They will be able to demonstrate their ability to skip count by organizing their base 10 blocks in the correct increments. At the end of the lesson students will master the ability to skip count and demonstrate their ability during the assessment on which they must score an 85% or higher to pass.
Introduction: To start of this lesson, the students will be reviewing how to skip count by 2’s. Then each student will be given their own baggy of base ten blocks. With these base ten blocks, the students will use the unit cubes to create groups of 2 and demonstrate their ability to count by 2’s. After the students have completed the activity they will watch three separate videos on how to count by 5’s and 10’s.
Array- Objects displayed in rows or columns.
Skip Counting- The process of counting objects in equal groups of two or more.
Equal Groups- Groups with the same number of objects.
Even Numbers- Any number that ends in 2, 4, 6, 8, or 0.
Odd Numbers- Any number that ends in 1, 3, 5, 7, or 9.
Repeated Addition- To add by the same number over and over.
Body of Lesson: Once the students have watched all three videos on how to count by 5’s and 10’s, the students will begin their first activity. For the first activity, the students will be using their own baggy of base ten blocks. As the students are creating their group’s of 5’s and 10’s, the teacher will be using the “I DO, WE DO, YOU DO” to make sure students are comprehending what they’re learning. When doing the “I DO, WE DO, YOU DO”, the teacher will first tell students the answer. Next the students will say the answer with the teacher. Lastly the students will say the answer by themselves. By doing this activity with the base ten blocks, students will be able to make groups of 5’s and 10’s, and they will also be able to count by 5’s and 10’s. Another activity the students will be doing will include completing a worksheet. The worksheet will require students to fill in the missing blanks. For example, the worksheet will have a caterpillar on it and on each section of the caterpillar there will either be a number or a blank spot. For all the blank spots, the students will have to fill in the missing number. If the students finish their worksheets early they are to play the “Grouping and Grazing” OER. This website can also be used as a way for students to practice counting by 5’s and 10’s outside of class.
Accommodations/ Modifications: For a visually impaired student.
- Allow for 50% additional time to complete assignments and/or tests
- Large print handouts
- Place student at the front of the classroom
- Highlight key directions
- Oral testing
- Daily feedback to student
- Assign shorter homework assignments
Multiple Intelligence(s) Addressed: For students who excel visually-spatially, there are videos and hands on activities to help them visually see what it is they are learning. The activities such as creating groups with the base 10 blocks allows the visual-spatial students see how the numbers increase by the given increment.
Summative Assessment: The assessment will be composed of questions requiring students to use their base 10 counting blocks to solve the problems and demonstrate their ability to skip count, and their knowledge of the vocabulary. The students will have 20 minutes to complete the attached assessment. Students will be expected to score an 85% or higher to pass the test.
Formative Assessment: Students will be given a variety of question in class and will be evaluated on how well they perform the tasks asked for example: students will be asked to do groups of 5 and 10 etc. to show their understanding of what was taught to them and to show what concepts they have mastered.
Informal: While students are using their base 10 blocks to practice counting up by 5s or 10s the teacher will walk around the classroom and observe whether or not the students are beginning to understand the concept of counting by increments.
