Activity 01
Chant Circle: Skip Count Rounds
Form a circle with students standing. Leader calls a starting number and count (e.g., twos from 10), and the group chants forwards then backwards around the circle. Switch leaders every sequence. Record chants on chart paper for reference.
What are the next three numbers when you count in twos: 4, 6, 8, ...?
Facilitation TipChant Circle: Begin with a slow, steady pace and gradually increase speed, modeling how to listen and echo accurately as a group.
What to look forWrite a number on the board, for example, 35. Ask students to write the next three numbers when counting forward by fives. Then, ask them to write the previous three numbers when counting backward by fives. Observe student responses for accuracy in applying the pattern.

Activity 02
Number Line Hop: Fives and Tens
Draw giant number lines on the floor with tape. Pairs take turns hopping forwards and backwards in fives or tens from random starts, calling numbers aloud. Switch roles after 10 hops and note patterns observed.
Can you count in fives from 5 all the way to 50?
Facilitation TipNumber Line Hop: Place masking tape markers on the floor to reduce distractions and ensure clear jumps of 5 or 10 units.
What to look forProvide students with a card that says: 'Count in tens from 20 to 70. How many tens are in the number 50?' Students write their answers and show their skip counting sequence on the back.

Activity 03
Bead String Relay: Twos Race
Provide strings and beads in small groups. Teams skip count in twos to string matching beads (e.g., 2,4,6), racing to 20 then backwards. Discuss why patterns repeat and extend to larger numbers.
How many tens are in the number 60?
Facilitation TipBead String Relay: Assign specific starting points on the string so each team practices different sequences without confusion.
What to look forPose the question: 'If you were counting a pile of 40 coins by twos, how many groups of two would you have? How is this different from counting them by tens?' Facilitate a brief class discussion, encouraging students to explain their reasoning using skip counting.

Activity 04
Card Flip Game: Mixed Counts
Create cards with starts and counts (e.g., 'Fives from 25'). In pairs, flip cards, skip count aloud three steps forward/backward, and check with mini whiteboards. Tally correct sequences for points.
What are the next three numbers when you count in twos: 4, 6, 8, ...?
Facilitation TipCard Flip Game: Use a timer to keep rounds short and focused, then rotate roles so all students get turns calling and responding.
What to look forWrite a number on the board, for example, 35. Ask students to write the next three numbers when counting forward by fives. Then, ask them to write the previous three numbers when counting backward by fives. Observe student responses for accuracy in applying the pattern.

Generate Complete Lesson→A few notes on teaching this unit
Teachers should balance rote practice with purposeful reasoning. Avoid rushing to abstract symbols like 2 + 2 + 2 = 6 before students can explain why 2, 4, 6, 8 skips by twos. Use backward counting and non-zero starts early to build flexibility. Research shows that pairing movement with auditory patterns strengthens memory, so incorporate chants alongside physical actions whenever possible.
Students will confidently count forwards and backwards in twos, fives, and tens from any starting point without hesitation. They will explain how these sequences relate to place value and use skip counting to solve simple grouping problems. Peer discussions will show they can articulate patterns, not just recite numbers.
Watch Out for These Misconceptions
During Chant Circle, watch for students who only count forward from zero or assume the sequence always starts at the beginning.
Pause the chant after each round and ask a student to start from a new number, such as 12 or 25, to reinforce varied starting points and reverse directions.
During Bead String Relay, watch for students who see twos, fives, and tens as unrelated sequences without noticing shared endings.
After the race, gather students to sort bead groups by color and pattern, then ask them to explain why sequences like 10, 20, 30 and 5, 10, 15 both end in zero.
During Number Line Hop, watch for students who skip over single digits when counting in tens, treating the sequence as whole jumps without units.
Have students physically place ten-frames on each jump, saying aloud 'one ten, two tens' to connect the count to place value understanding.
