Fresh learner checks

Success: multiply hundreds, tens and ones by a single digit without losing a zero place. Prepare: 324×6 model, three place columns. Codes: AC9M5N06.

  1. Recall · 2 min. Ask for 3×6 and 30×6, then why they differ. Key: 18 and 180; the second has tens.
  2. Model · 5 min. Build 324×6=300×6+20×6+4×6=1,800+120+24=1,944. Circle the sum, not a concatenation of partial answers.
  3. Guide · 6 min. Test 407×8 = 400×8 + 0×8 + 7×8 = 3,200+56=3,256. Ask whether 0 in the tens place can be silently turned into a 7 tens. Key: no.
  4. Choose · 7 min. Day 12 A/B/C learner card. Permit place-value blocks, a typed table, vertical algorithm or spoken partitions; require each part to retain its value.
  5. Exit · 3 min. “Which is a useful check for 324×6: near 1,800 or near 18,000?” Key: near 1,800. If 18,000, rebuild the hundreds group.
  6. Record · 2 min. Mark arithmetic versus place-value error; a correct answer without inspectable strategy needs a question, not an automatic failure.
