Subject Area: Mathematics
On-Level Grade: 2 Reteach: 3rd-Grade Enrich: 1st=Grade
Domains & Clusters:
Operations and Algebraic Thinking
Work with equal groups of objects to gain foundations for multiplication.
Numbers and Operations in Base Ten
Understand place value
Use place value understanding and properties of operations to add and subtract
MAFS.2.OA.3.3 Determine whether a group of objects (up to 20) has an odd or even number of members, e.g., by pairing objects or counting them by 2s; write an equation to express an even number as a sum of two equal addends (GO MATH! LESSON 1.1)
MAFS.2.NBT.1.3 Read and write numbers to 1000 using base-ten numerals, number names, and expanded form (GO MATH! LESSONS 1.3, 1.5)
MAFS.2.NBT.1.2 ~ Count within 1000; skip-count by 5s, 10s, and 100s (GO MATH! LESSON 1.9)
MAFS.2.NBT.2.5 ~ Fluently add and subtract within 100 using strategies based on place value, properties of operations, and/or the relationship between addition and subtraction.
even ~ numbers that show pairs with no ones left over
odd ~ numbers that show pairs with one ones left over
digits ~ 0, 1, 2, 3, 4, 5, 6, 7, 8, and 9. In a 2-digit number, you know the value of a digit by its place.
Objectives / Level 3 Learning Targets:
Engage and differentiate your child or students in a challenging way that will allow them to:
Classify numbers up to 20 as even or odd (GO MATH! LESSON 1.1)
Use place value to describe the values of digits in 2-digit numbers (GO MATH! LESSONS 1.3)
Write 2-digit numbers in word form, expanded form, and standard form. (GO MATH! LESSON 1.5)
Extend counting sequences within 1,000, counting by 1s, 5s, 10s, and 100s. (GO MATH! LESSON 1.9)
Fluently add and subtract within 100
How are even numbers and odd numbers different? (LESSON 1.1)
How do you know the value of a digit? (LESSON 1.3)
How do you know the value of a digit? (LESSON 1.5)
How do you count by 1s, 5s, 10s, and 100s with numbers less than 1,000? (LESSON 1.9)
How do you fluently add and subtract within 100?
Materials Needed: Make sure you have these materials ready:
Make two copies of “Too Many Monkeys Jumping on the Bed” for each student. (one for before the lesson and one for after)
Make one copy of “I’m a Jumping Monkey” student evidence of learning coloring sheet.
(optional) base ten blocks, connecting cubes, counters, marbles, skittles, etc. to help the student organize his or her thinking in concrete ways
Time Required: 10-15 minutes whole group, 10-30 minutes small group centers
Recommended Grade Range: K-5: K-1 Enrichment; 2 On Level; 3-5 Reteaching
Assessment: Too Many Monkeys Jumping on the Bed ~ used as an Exit Slip
Enrichment: Have the students challenge themselves and each other by changing the starting number of monkeys (50) jumping on the bed and filling in the blanks with the new answers.
This would be considered ABOVE GRADE LEVEL or LEVEL 4 and would you allow you to assess whether your child or student has truly mastered these skills by imagining what the new answers would be all on their own.
