Grade 2 Math Flashcards and Task Cards: Measuring Length

How to Present

• Use the word cards to pre-teach and review the length words (2 per A4 page — print and cut). Use the 16 task cards for Scoot or group work; children write answers on the recording sheet, and the answer key is on the same page.

Games & Speaking Activities

• Word wall: put the word cards next to a big classroom ruler for the whole unit.
• Scoot: put the task cards around the room; children move every minute and write their answers.

Teacher Tips

The two biggest ruler mistakes are starting at the edge of the ruler (or at 1) instead of 0, and writing the end number when the object does not start at 0. Before the first ruler lesson, let every child find the 0 on their own ruler and mark it with a dot of colour, and use the paper rulers in Teacher Resources for the first practice — they start exactly at 0 and show only whole centimetres. For "not at 0", have children put a finger on the start and count the jumps aloud: "1, 2, 3 … 6 — 6 cm." Ask "7 what?" every time a child forgets the unit. Print the worksheet at 100% (actual size) so the ribbons in Part E measure correctly with a real ruler.

Learning Objectives

• Compare and order lengths using longer, shorter, taller, longest and shortest, lining up the ends.
• Measure with cubes and paper clips with no gaps or overlaps.
• Measure and draw lengths in centimetres with a ruler, starting at 0.
• Find a length that does not start at 0 by counting the spaces or end − start.
• Choose cm or m, know that 1 m = 100 cm and make sensible estimates.
• Find how much longer one length is than another.
• Solve one-step add and take-away length problems and write the unit.

Differentiation

Support: Use the paper rulers (whole centimetres only) and colour the 0. Let children lay cubes along the ruler to see each centimetre, and count the jumps with a finger when an object does not start at 0. Give sentence frames ("It is ___ cm long." "The ___ is longer than the ___." "We use cm / m."). Pair a child who is new to English with a partner who models the sentences.
Extension: Measure lengths up to 30 cm with a longer ruler, order 5 classroom objects by length, solve two-step problems, or measure the classroom in metres with a 1 m string. Fast finishers can play Measure Master (Length Problems mode) or do the My Body measuring task.

Assessment

Check the recording sheets with the answer key: cards 1–3 compare and measure with cubes, 4–7 read the ruler (6–7 do not start at 0), 8–11 cm or m and estimates, 12 metres, 13–15 how much longer and length problems, 16 Check it!
