a. Skip count by 2s up to 30. Color these numbers BLUE.

b. Skip count by 5s up to 50. Color these numbers YELLOW.

c. Skip count by 10s up to 100. Encircle these numbers in GREEN.

d. Which numbers up to 30 have both blue and yellow?

Answer: , ,

e. Look at column 10 (numbers ending in 0). How many numbers end in 0?

f. What is the smallest number that is in the 2s, 5s, and 10s pattern?

💡 Pattern Secret: Notice that every number that ends in 0 is shared by the 2s, 5s, and 10s skip counting patterns!

• M1NS-Id-5: Understands place value (tens and ones) in composing and decomposing two-digit numbers.
• M1NS-Ie-7: Orders numbers up to 100 in ascending (least to greatest) and descending (greatest to least) order.
• M1NS-IIa-9: Identifies and extends skip counting patterns (2s, 5s, 10s, 3s, 4s) using the 100s chart.

Part E: 100s Chart Investigation Answers
d. Both Blue & Yellow: 10, 20, 30 (Common multiples of 2 & 5)
e. Numbers ending in 0: 10 numbers (10, 20, 30, 40, 50, 60, 70, 80, 90, 100)
f. Smallest number in all 3 patterns: 10

📊 Grade 1 Competency Diagnostic Matrix

Skill Domain	Mastery (85–100%)	Developing (60–84%)	Target Intervention (<60%)
Place Value Comparison	Instantly compares decomposed tens & ones without misreading digit order.	Correctly compares plain 2-digit numbers; pauses on '9 ones and 2 tens'.	Use base-ten blocks (flats and units) to visually build both quantities.
Ascending / Descending	Accurately orders 5 numbers; never confuses least with greatest.	Understands ascending; makes minor ordering slips on descending sets.	Have learner circle the tens digits first, then arrange on an open number line.
Skip Counting on Chart	Identifies common multiples (10, 20, 30) and column patterns automatically.	Colors 2s and 5s accurately; needs guidance to see overlapping shaded boxes.	Practice rhythmic clapping or dot-painting on the physical 100s chart.

💡 Teacher & Parent Facilitation Questions:

• Place Value Reversal: Watch for items like "9 ones and 2 tens". Prompt the learner: "Which number represents the tens? Which represents the ones? Let's write the tens first!"
• Hungry Alligator Trick: Remind Grade 1 learners that the open mouth of > and < always "eats" the larger quantity.
• Hundred Chart Columns: Have the child notice that all numbers in the 10s column end in 0, and all numbers in the 5s column end in 5 or 0.
