Maths starters for the classroom
A starter can help you see what children remember before the main lesson. Choose one prompt, give quiet thinking time and then invite a drawing, calculation or explanation. These twenty-five starters are grouped by a suggested Class range, not a compulsory teaching sequence. Follow your school's textbook and the learning you have actually taught.
Write the question where everyone can see it. Accept a spoken answer, a pointed choice or a drawing before asking for a written explanation. Keep a mistaken answer available for discussion without naming or embarrassing its author.
For Classes 1 and 2
1. Number of the day
Choose 14. Ask children to show it with counters, tens and ones, and an addition statement. One ten and four ones, 10 + 4 and 7 + 7 all represent 14. Ask how they know each representation has the same value.
2. Make ten
Show six counters. “How many more make ten?” The answer is four: 6 + 4 = 10. Hide the four and ask children to explain the missing part. Swap the visible part to practise another bond.
3. Quick-look dots
Briefly show seven dots arranged as five and two. Children explain what they saw: 5 + 2 = 7. Show the arrangement again to check. The aim is recognising groups, not rewarding the child who shouts first.
4. What comes next?
Write 2, 5, 8, 11 and say that the rule is “add 3 each time”. The next two numbers are 14 and 17. Stating the rule avoids pretending that a short number sequence can have only one possible continuation.
5. Before and after
Ask for the number just before 40 and just after it: 39 and 41. Children can move a counter on a number line. Ask what changes when moving from 39 to 40: nine ones become a new ten.
6. Two ways to make thirteen
Use 13 counters to show 8 + 5 and 7 + 6. Both totals are 13. Ask children to move one counter from the group of eight to the group of five and explain why the total stays unchanged.
7. Pair check
Give partners 11 counters to arrange in pairs. Five pairs leave one counter, so 11 is odd. With 12 counters, six complete pairs show an even number. Let children demonstrate before introducing a last-digit shortcut.
8. Pretend price
A paper price label says ₹12. A customer pays ₹20. The change is ₹8 because 12 + 8 = 20. Use drawn rupee cards or counters; no real money is needed.
For Classes 3 and 4
9. Missing part
Write □ + 9 = 29. The missing number is 20. Children can subtract 9 from 29 or use 20 + 9 = 29. Ask them to substitute their answer into the original statement to check it.
10. Bridge a ten
Ask for 28 + 7. Split 7 into 2 and 5: 28 + 2 = 30, then 30 + 5 = 35. Compare this with counting on seven steps. Which method keeps the calculation simpler to track?
11. Near a round number
Find 46 + 19 by adding 20 and subtracting 1: 46 + 20 = 66, then 66 1 = 65. Ask why the adjustment is subtraction, not addition. Check by splitting 19 into 10 and 9.
12. Place-value swap
Compare 405 and 450. Both have four hundreds; the tens settle the comparison, so 450 is larger by 45. Ask why the zero in 405 is important. It records that there are no tens in that place.
13. Array flash
Draw three rows of seven dots. There are 21 dots: 3 7 = 21. Turn the drawing to see seven rows of three. The total stays 21, although the row description changes.
14. A helpful table
If 5 8 = 40, what is 6 8? Add one more group of eight: 40 + 8 = 48. Ask children to label the extra row in an array so the connection is visible.
15. Sharing or grouping?
Use 24 counters. Share among four children: six each. Now make groups of four: six groups. Both use 24 4 = 6, but the answer describes different things. Ask children to name the unit each time.
16. Clock choice
Draw a clock showing 3:45. It is quarter to four, not quarter past three. Point to the 15 minutes still needed to reach 4:00. A paper clock with movable hands makes a useful check.
17. Rectangle route
A rectangle is 6 cm long and 4 cm wide. Its perimeter is 6 + 4 + 6 + 4 = 20 cm. Children trace the boundary. If area is already taught, contrast it with 6 4 = 24 cm².
18. Estimate, then calculate
For 198 + 203, use nearby hundreds to estimate about 400. The exact answer is 401. Discuss why an estimate is not an incorrect exact answer: it answers a different, approximate question.
For Class 5
19. Three equal parts
A bar has three equal sections totalling 48. Each section is 16; two sections are 32. Ask children to mark the whole before dividing, and then check 16 + 16 + 16 = 48.
20. Same-sized wholes
Compare and of the same-sized sheet. Three-fourths is larger because one half equals two-fourths (two quarters). Children can fold or draw to verify. Different-sized wholes would need a different comparison.
21. Fraction of a collection
Find of 20 counters. One-fifth is 20 5 = 4, so three-fifths are 3 4 = 12. Check that the five equal groups together contain all 20 counters.
22. Factor pairs
Find the positive factor pairs of 24: 1 and 24, 2 and 12, 3 and 8, 4 and 6. These give the factors 1, 2, 3, 4, 6, 8, 12 and 24. Ask how a systematic search avoids duplicates.
23. Read the bar chart
Draw three bars labelled A, B and C with heights 8, 12 and 10 on a clearly marked scale. B is highest, the total is 30, and B exceeds A by 4. Children must use the scale, not merely count grid squares.
24. Addition hive
Write 58, 27, 85, 34 and 46 in five cells. The statement is 58 + 27 = 85. Check by adding 50 + 20 and 8 + 7: 70 + 15 = 85. Invite an inverse check: 85 58 = 27.
25. An optional lakh bridge
Use this only if your school's book includes lakhs: many private-publisher books teach them in Class 5, while the NCERT Class 5 book works with five-digit numbers rather than lakhs. Write 1,00,000 and read “one lakh”. Ten groups of 10,000 make 1,00,000. Contrast the comma positions with 10,000. This is an extension, not a requirement for every Class 5 child.
Indie's challengeA child says 46 + 19 = 67 because they added 20 and then added 1. How would you help them check? Show the answer
Adding 20 has already added one too much, so subtract 1: 46 + 20 1 = 65. Check another way: 46 + 10 + 9 = 56 + 9 = 65.
For longer practice, use classroom games or printable worksheets. Use reasoning prompts to develop the explanation after a starter.
