Ten Hop Week One Teacher Guide Tier 2 Math Intervention • Standard 1.NBT.C.5
Ten Hop Foundations: Teacher Guide
Week 1 Facilitation • 15 Minutes Daily • Focus: Place Value Structure to Mental Calculation
Days 1 – 5
Daily 15-Minute Intervention Structure
Step 1: Oral Warm-Up (3 Min) Choral counting by tens off the decade (e.g., 4, 14, 24, 34). Identify digit shifts.
Step 2: Guided Model (7 Min) Concrete base-ten rods to number grid vertical jumps. Explicit teacher verbalization.
Step 3: Quick Check (5 Min) Paired game practice or daily practice task. Record immediate mastery notes.
Day 1: Finding 10 More (The Tens Place Jumps Up)
Core Objective: +10 without counting by ones
Direct Instruction Script: "Look at 34. How many tens? 3 tens. How many ones? 4 ones. When we add 10, we add exactly one ten rod. Now we have 4 tens, but our 4 ones did not change. 10 more than 34 is 44."
Prompting Questions:
• "What digit changes when we find 10 more?" (The tens digit increases by 1)
• "Did the ones digit change? Why not?" (We only added tens, zero ones)
Practice Set: Model with 23, 56, 71. Student sheet: Day 1 section.
Day 2: Finding 10 Less (The Tens Place Jumps Down)
Core Objective: -10 without counting backwards by ones
Direct Instruction Script: "Take 65. If I want 10 less, I remove one ten rod. The 6 tens become 5 tens. What happened to the 5 ones? Nothing! 10 less than 65 is 55. We jump one row up on our number chart."
Prompting Questions:
• "If you have 48, what is 10 less?" (38 — tens drops from 4 to 3)
• "Why does counting backwards ten times waste time?" (We can simply decrease the tens by one)
Practice Set: Model with 82, 45, 19. Student sheet: Day 2 section.

Days 3 through 5 Instructional Steps • Diagnostic Corrective Table
Page 2
Day 3: Mixed Practice • Alternating 10 More and 10 Less
Focus: Listening carefully to operation cues
Routine: Flash number card (e.g., 37). Call out either "More!" or "Less!" Students hold up thumbs up for 47 or thumbs down for 27, then state the number aloud in complete sentence: "10 more than 37 is 47."
Day 4: Fading Visual Models (Transition to Pure Mental Math)
Focus: Mental imaging of tens change
Routine: Cover the number grid. Ask students: "Close your eyes. Picture 52 in your mind. Change the tens digit by adding one ten. What is the new number? (62). Now take 52 and take away one ten. (42)." Introduce the partner game "Ten Grid Target Game."
Day 5: Week 1 Checkpoint & Error Analysis
Focus: Formative progress check
Routine: Students complete Day 5 Mid-Check (6 items). Teacher observes response speed. Any student taking >5 seconds per item or counting on fingers receives targeted reteaching on Day 6.
Diagnostic Misconceptions & Targeted Teacher Fixes
Observed Error Root Misconception In-the-Moment Scripted Correction Adding 10 to ones place (e.g., 24 + 10 = 214 or 34) Student confuses tens and ones column place value. "Ten is 1 ten and 0 ones. Look at the tens place in 24. It is a 2. Add 1 to the 2. The ones stay 4. The number is 34." Counting up/down 10 times by ones Lack of unitizing; treating 10 as ten individual single units rather than one unit of ten. "Stop finger counting. Ten is one big jump! What is 1 more than 4 tens? 5 tens! Keep the 3 ones. 53!" Subtracting 10 from teens (e.g., 10 less than 17 is blank or 70) Student is confused when tens place becomes zero. "17 has 1 ten and 7 ones. If we take away the 1 ten, how many tens are left? 0 tens! Only 7 ones remain. 10 less is 7."
Standard 1.NBT.C.5 Academic Vocabulary
Tens Digit: The digit showing groups of ten.
Ones Digit: The digit showing remaining ones.
Ten More: Add 1 ten (+10). Tens increases by 1.
Ten Less: Remove 1 ten (−10). Tens decreases by 1.

Week 2 Facilitation • 15 Minutes Daily • Focus: Automaticity, Word Problems & Assessment
Days 6 – 10
Daily 3-Minute Rapid Fire Oral Protocol
Conduct around the circle. Point to student, state starting number, and say "Up" (+10) or "Down" (−10). Student must respond within 3 seconds without fingers. Target goal: 10 correct responses in 60 seconds per student pair.
Day 6: Rapid Retrieval & Mixed Speed Sets
Focus: Sub-3 second retrieval
Script: "Today we are building speed. You already know that 10 more changes the tens digit up by 1, and 10 less changes it down by 1. Do not draw pictures or count fingers. Trust your place-value brain."
Practice: Administer Day 6 Fluency Sprint on student worksheet. Track completion time.
Day 7: Missing Number Equivalence Puzzles
Focus: Algebraic flexibility (e.g., ___ + 10 = 53)
Script: "What if the mystery number comes first? 'Mystery number plus 10 is 53.' If adding 10 gave us 53, what number did we start with? We work backwards! 10 less than 53 is 43. Check: 43 + 10 = 53."
Practice: Model unknown start vs. unknown change. Student sheet: Day 7 section.
Day 8: Contextual Word Scenarios & Explanation
Focus: Standard 1.NBT.C.5 explanation requirement
Script: "Elena scored 47 points. Leo scored 10 fewer points. How many points did Leo score? How did you solve it in your head?" Require students to explain using place value language: "I knew 10 less than 4 tens was 3 tens, so 37."

Day 9: Partner Fluency Game • Ten Sprint Match Game
Focus: Competitive fluency reinforcement
Pair students to play "Ten Sprint Match Game." Students draw challenge cards and mentally compute 10 more or 10 less to claim squares on the grid. Teacher circulates to conduct informal fluency observations prior to Day 10 assessment.
Day 10: Formal Post-Assessment Administration
Focus: 1.NBT.C.5 Mastery Verification
Protocol: Distribute the 1.NBT.C.5 Post-Assessment. Read directions aloud. Allow 10-12 minutes for independent completion. Observe students for reliance on fingers or scratch counting. Note any students who still compute by ones.
