Strategy Touch Math (Digits 1–10)
Setting Whole Group & Pairs
Learning Objectives
Solve truck delivery word problems modeling joining (addition), separating (subtraction), and comparing (difference).
Locate and count multisensory Touch Points accurately on digits 1 through 10 to add and subtract without finger-counting errors.
Essential Questions
"How does cargo movement (loading vs. unloading) tell us whether to add or subtract? How do Touch Points turn any written digit into a built-in counting tool?"

Three Delivery Story Schemas
Joining (Loading)
Truck begins with cargo; warehouse loads more crates. Total increases.
Start + Loaded = Total
Separating (Unloading)
Truck leaves terminal full; drops crates at supermarket. Remainder decreases.
Total - Delivered = Left
Comparing (Weigh-In)
Dump Truck A holds 8 pallets; Flatbed B holds 5. Finding "how many more/fewer".
Greater - Lesser = Difference

Pacing & Step-by-Step Instructional Delivery
Classroom Sequence
1. Dispatch Depot Hook & Warm-Up (10 min)
Engage
Introduce the class as "Junior Cargo Dispatchers." Model a toy truck or visual flatbed: "Truck 104 starts with 4 shipping containers. At Terminal B, the forklift loads 3 more containers. Did cargo get added or dropped off?" Guide students to trace Touch Points on the number 3 while saying "4... 5, 6, 7!"
2. Explicit Modeling: 3 Schemas + Touch Counting (15 min)
Instruct
Teach the 3 dispatch clues: Joining ("loaded onto", "picked up"), Separating ("delivered", "dropped off", "unloaded"), and Comparing ("how many more crates than", "how many fewer"). Model counting on using Touch Points for digits 1–9. For 10, emphasize: "10 is 1 ten-bundle; tap the 1 once, 0 has zero points!"
3. Guided Practice: Dispatch Mission Cards (15 min)
Collaborate
Students work in partner trucker pairs with the Guided Practice Document. Teacher circulates providing prompt cards: "Read the story, circle key cargo numbers, label the action (Join / Separate / Compare), and use the Touch Points to tally the exact load count."
4. Independent Freight Hauler Work & Assessment (15 min)
Evaluate
Students independently solve the Freight Haulers Worksheet. Formative checkpoint: check whether students touch points correctly on double-dot digits (6, 7, 8, 9) and write complete equations with operational symbols (\(+\), \(-\), \(=\)).
5. Cargo Inspection Debrief (5 min)
Synthesize
Ask: "If Semi Truck A has 9 barrels and Flatbed B has 6 barrels, which operation helps us compare their loads?" Students give thumbs up/down and share mental touch count steps.
Tiered Differentiation
Support (Tier 1): Provide tactile cargo blocks (Unifix cubes) alongside touch point numbers. Restrict numbers to sums within 10.
On-Level (Tier 2): Use pencil tap on Touch Points without counting cubes. Solve joining and separating with unknown totals or changes.
Extension (Tier 3): Multi-step truck route: 2 pickups then 1 delivery. Compare three freight loads and calculate total convoy weight.
Common Misconceptions
Comparing Confusion: Students see "more" in a comparison problem and mistakenly add. Remedy: Emphasize "Weigh Scale" matching pairs.
Double Dot Drift: On numbers 6–9, students tap double dots only once. Remedy: Chant "Touch the dot, touch the ring; double dots make numbers sing!"
The Digit 10: Students look for 10 individual dots on '10'. Remedy: Remind that 10 is 1 ten and 0 ones.

MISSION 2 Separating Action • Lumber Drop-Off
Subtraction (−)
Story: Flatbed Flora departed the forest mill carrying 8 giant logs. At City Lumber Yard, she unloaded 3 logs. How many logs remain on Flora’s truck?
Unload Flora's Cargo: Cross out 3

Cargo Remaining Sentence: Flora has logs left on the truck.
MISSION 3 Comparing Action • Weigh Station Match-Up
Comparison (−)
Story: At Highway Weigh Station 9, Semi Mack weighs in with 7 freight pallets. Box Truck Ben weighs in with 2 freight pallets. How many more pallets does Mack have than Ben?
Pallet Line-Up Comparison
Mack: 1 2 3 4 5 6 7
Ben: 1 2 ← Difference zone
Subtract the matching pair (2) from Mack's 7.
Write Comparison Equation:
7 − 2 =
Difference Sentence: Mack carries more pallets than Ben.

DELIVERY 1 Cement Mixer Run • Solution
Schema: Joining (Loading)
Model & Equation Solution:
6 + 3 = 9
Complete Sentence: Carlos has 9 sacks of cement in all.
Touch Math Counting Verbalization:
1. Start with the greater number in head: "6" .
2. Touch 3 points on digit 3 while counting on: "7" (top), "8" (middle), "9" (bottom).
Teacher Watch: Ensure student doesn't count the starting 6 on fingers; teach them to say "6" and tap on.
DELIVERY 2 Fresh Produce Drop-Off • Solution
Schema: Separating (Unloading)
Model & Equation Solution:
9 − 4 = 5
Complete Sentence: Maya has 5 crates of apples left.
Touch Math Counting Verbalization:
1. Start with the total load: "9" .
2. Touch 4 points on the subtrahend (4) counting backward: "8" (top-left), "7" (top-right), "6" (bottom-left), "5" (bottom-right).
Teacher Watch: Look for reverse counting fluency. If backward counting is difficult, prompt: "What comes right before 9? 8... 7... 6... 5!"
DELIVERY 3 Pipe Yard Comparison • Solution
Schema: Comparing (Difference)
Model & Equation Solution:
8 − 5 = 3
Complete Sentence: The Semi carries 3 more pipes than the pickup.
Touch Math Counting Verbalization:
1. Identify the greater load (8) and the lesser load (5).
2. Count back 5 touch points from 8: "7, 6, 5, 4, 3" .
Teacher Watch: Clarify that "more" does not always mean add! Here we match up the 5 pipes they both have, leaving 3 extra.
