Teacher Cheat Sheet — Session 3: Counting What We Find

Data Science for Young Minds · Grade 1 · Ages 6–7

~45 min Ages 6–7 Session 3 of 8 ND-Friendly

Session Agenda

Time	Block	What's Happening
0–5	Hook	Teacher counts 8 objects aloud, pointing one by one. Miscounts one on purpose. "Did I count right?"
5–15	Teach	Demonstrate one-to-one counting: touch each object, say one number. Show dot recording method.
15–28	Activity	Students use Session 2 sorted groups — count each group, record with a number AND draw dots.
28–33	Brain Break	Count together as a class: jump 5 times, clap 3 times, stomp 7 times. Move your body to count!
33–40	Work	Worksheet: write number, draw dots to match, circle to check.
40–43	Recap	"Which group had the most? Which had the fewest?" Preview comparison words.
43–45	Close	Preview: "Next time we will ask the whole class a YES or NO question!"

Key pacing note: Demonstrate one-to-one counting with deliberate, slow pointing. Many 6-year-olds skip objects or count one object twice. The physical touch + verbal count is the whole lesson. Allow recounting — it is not a mistake, it is learning.

Materials Needed

Prepare before class:

Sorted objects from Session 2 (or fresh bags) Pencils (for pointing while counting) Student worksheets Dot stickers or crayons for dot recording Large number cards 1–10 posted on wall

Tip: If students don't have their Session 2 sorts, quickly re-sort as a class before counting. Takes 3 min. The counting activity works best with groups of 3–8 objects — not too many, not too few.

Key Vocabulary

Count — say one number for each object as you touch it

How many — the question we ask to find the total

Group — all the things sorted together by a rule

Total — the number of objects in a group when you finish counting

Number — the word (and symbol) that tells how many

Discussion Questions + Teacher Notes

"How do we make sure we count every object — and don't count any twice?"
→ Touch each one and say one number. Move each object to a "counted" pile as you go, or draw a dot for each one. Demonstrate both strategies. Let students try both and choose what helps them.
"What happens if I count the same one twice by accident?"
→ I get the wrong total! That's why we touch and move — physical one-to-one helps prevent errors. Deliberately miscount in your hook to make this point memorable.
"After counting, which group has the most objects? How do you know?"
→ Look at the numbers! This plants the seed for Session 6's comparison work. Let students compare two groups first — just two, not all three. Comparison vocabulary (more, fewer) will be formal in Session 6.
"Does counting in a different order change the total?"
→ No! This is a crucial math concept (cardinality). Count the same 5 buttons starting from the red one, then from the blue one — same answer. Students who discover this are often delighted.
"How could we SHOW how many are in each group without using words?"
→ Draw dots! One dot = one object. This is the foundation of pictographs (Session 5). Introduce dot recording now as a physical, intuitive way to represent counts.

Counting Activity — Setup Guide

Students use their sorted groups from Session 2. If fresh objects: do a quick 3-min sort by color first. Each student counts their sorted groups one at a time, writes the number, then draws that many dots to double-check.

Steps (demonstrate ALL first with YOUR objects):

Pick one sorted group. Touch each object — say a number out loud.
After counting: write the total number on your worksheet.
Draw that many dots in the dot box — one dot per object.
Count the dots to check. Do they match?
Repeat for each sorted group.

Key debrief: "Look at your numbers for each group. Which group has the biggest number? That's your biggest group!"

Allow students to use a pencil as a pointer. Allow recounting without comment — just say "great, count it again to be sure!"

Opening Hook

Count 8 objects aloud on the board, deliberately touching one twice so you get "9."

"I counted 9! Does that sound right?"

Ask a student to recount. Celebrate when they find the error.

→ The deliberate mistake makes the lesson concrete: counting carefully matters because errors change the number.

Brain Break

Count with your body! (~28 min)
"Jump 5 times — count out loud!" then "Clap 3 times!" then "Stomp 7 times!"

60 seconds. Returns focus and reinforces one-to-one counting in a kinesthetic way. Vary the numbers to match the range in the class data.

ND-Friendly Tips

Pointing tool— Give students a pencil or finger to touch each object as they count. Physical touch prevents skipping and double-counting.
Move-to-counted pile — Students who lose their place can move each counted object to a "counted" pile. Physical separation is more reliable than memory.
Allow recounting — Never say "you already counted it." Recounting is self-correction and should be praised.
Graph paper option — Students who struggle to space dots evenly can draw one dot per square on graph paper. Much easier to check alignment.
Number cards on wall — Post 1–10 number cards with dot patterns. Students who forget how to write a numeral can look up.
