10. Apply knowledge of using rules to create patterns to solve problems (A)

# data[].attributes.attachment_link.description
Lesson objective: Apply knowledge of using a given rule to create a pattern to a real-life problem. This lesson provides an opportunity for students to apply their knowledge and understanding of patterns to a real-life situation.

9. Generate patterns and make observations (FP)

# data[].attributes.attachment_link.description
Lesson objective: Generate patterns using the four operations and make observations on the features of the pattern. This lesson helps to build fluency with generating patterns and making observations on patterns. Pattern rules with variables are used here because it continues students' work with variables and patterns from third grade and develops it with making observations.

8. Create patterns and describe their features (C)

# data[].attributes.attachment_link.description
Lesson objective: Create patterns using a given rule and find features of patterns. Students bring prior knowledge of arithmetic patterns from 3.OA.D.9. This prior knowledge is extended to creating patterns and analyzing those patterns in order to make observations about its features.

7. Apply knowledge of prime and composite numbers (A)

# data[].attributes.attachment_link.description
Lesson objective: Apply knowledge of factors and prime and composite numbers to solve problems in real-world situations. This lesson provides an opportunity for students to apply their knowledge and understanding of prime and composite numbers to a real-life situation.

6. Use a factor chart to determine if a number is prime or composite (FP)

# data[].attributes.attachment_link.description
Lesson objective: Use a factor chart to determine if a number is prime or composite. This lesson helps to build procedural skill with determining if a number is prime or composite. A t-chart is used here because it supports students' work with factor pairs and allows students to list factor pairs in an organized way.

4. Determine prime and composite numbers (C)

# data[].attributes.attachment_link.description
Lesson objective: Understand that prime numbers are whole numbers greater than 1 that have only 2 factors. Understand that composite numbers are whole numbers greater than 1 with more than 2 factors. Students bring prior knowledge of multiplication and division within 100 and factors and multiples from 3.OA.A.3 and 4.OA.B.4.

3. Use skip-counting to find multiples (FP)

# data[].attributes.attachment_link.description
Lesson objective: Find multiples by skip-counting This lesson helps to build fluency with finding multiples of whole numbers. Skip-counting is used here because it highlights all of the multiples of a factor with a strategy students have used previously in Grade 3. This work develops students' understanding that a whole number is a multiple of its factors.

2. Use an area model and T-chart to determine factors (FP)

# data[].attributes.attachment_link.description
Lesson objective: Find factors of a whole number using area models or a t-chart. This lesson helps to build procedural skill with finding factors of whole numbers. Area models are used here because it supports students' knowledge of multiplication representation from third grade. A t-chart is used here because it develops fluency in determining factors.
