Activity 01
Manipulatives: Counter Take-Away
Give each pair 10 counters and two cups. One student sets a starting number in the first cup, the other takes some away to the second cup, then both count and write the sentence. Switch roles for three rounds. Pairs share one example with the class.
What does subtraction mean and when do we use it?
Facilitation TipDuring Counter Take-Away, circulate and listen for students to verbalize the action as they remove counters, reinforcing the connection between the physical act and the number sentence.
What to look forProvide students with 8 counters. Ask them to 'take away' 3 counters and record the subtraction number sentence. Then, ask them to find the difference between 8 and 5 counters and record the sentence.

Activity 02
Ten-Frame Cross-Out
Draw ten-frames on paper with starting dots. Students use dry-erase markers to cross out the subtrahend amount, count remaining dots, and record the equation. Complete five frames individually, then compare with a partner.
How is subtraction related to addition?
Facilitation TipFor Ten-Frame Cross-Out, ask students to describe the remaining counters as both the difference and the starting number minus the crossed-out amount to build dual understanding.
What to look forPresent a picture of 5 birds on a branch, with 2 flying away. Ask students to write the subtraction number sentence that matches the picture. Then, ask: 'What does the minus sign tell us to do?'

Activity 03
Subtraction Story Relay
Divide class into teams. Teacher reads a story prompt like '7 birds, 3 fly away.' First student in line acts it out with fingers, writes equation on board, tags next. Continue for 10 stories.
How do we write a subtraction number sentence?
Facilitation TipIn Subtraction Story Relay, pause groups to discuss why certain objects are being subtracted and what the result represents in the story context.
What to look forWrite '3 + 4 = 7' on the board. Ask students: 'How can we use this addition fact to help us write a subtraction sentence?' Guide them to discover 7 - 4 = 3 and 7 - 3 = 4.

Number Line Hops
Mark number lines 0-10 on floor. Call 'Start at 8, take away 3.' Students hop back, land on answer, say equation. Rotate leaders for calls.

Generate Complete Lesson→A few notes on teaching this unit
Teach subtraction within 10 by starting with concrete manipulatives before moving to symbols, ensuring every abstract sentence has a physical counterpart. Use consistent language like 'take away' and 'how many left' to build clarity. Avoid rushing to abstract recording, as students need time to internalize the relationship between actions and symbols. Research shows that pairing subtraction with addition facts (inverse operations) strengthens both skills, so weave this connection into every activity.
Successful learning looks like students confidently modeling subtraction with objects, writing accurate number sentences, and explaining the meaning of the minus sign. They should recognize subtraction in real contexts and use it flexibly as either take-away or difference between quantities.
Watch Out for These Misconceptions
During Counter Take-Away, watch for students who always count down from the first number, ignoring the context of the problem.
Ask these students to recount their actions with the counters, saying aloud, 'I started with 6, then I took away 3, so I have 3 left.' Use the counters to reinforce the take-away meaning.
During Ten-Frame Cross-Out, watch for students who confuse the operation by writing the wrong subtraction sign or reversing the numbers.
Have students point to the ten-frame and say the fact aloud before writing, emphasizing that the larger number comes first when taking away. Model writing the sentence as they speak.
During Subtraction Story Relay, watch for students who subtract a larger number from a smaller one without recognizing it as impossible in the context.
Pause the relay and ask, 'Can we take 5 toys away from 3 toys? What would that look like with your story objects?' Guide them to adjust the story so the subtraction makes sense.
