Teach next

Across a ten

8 of the 14 students who tried it are not fluent yet: 3 stuck, 5 getting there. The most common mistake is smaller digit from the larger, as in 62 − 27 → 45 instead of 35. 8 students make it. The weakest kind of problem is subtraction, across a ten: 79% right over 94 answers.

Warm-up for tomorrow: 32 − 3, 32 − 6, 35 − 7

Small groups

Students grouped by the same gap. Each group has something to teach, not just a score.

  • Group 1 · 4 students

    Off by one

    Addition and subtraction up to 20

    Eli, Noah, Beck, Ruben

    8 + 7 → 16, not 15. Counting on fingers, or starting the count on the wrong number. Fact practice, not method.

  • Group 2 · 4 students

    Off by one

    Adding and subtracting tens

    Gus, Cleo, Leo, Priya

    8 + 7 → 16, not 15. Counting on fingers, or starting the count on the wrong number. Fact practice, not method.

  • Group 3 · 4 students

    Smaller digit from the larger

    Across a ten

    Farah, Isla, Jonah, Quinn

    62 − 27 → 45, not 35. Borrowing is not happening at all. Usually the same student does it at every size.

  • Ready to move up · 4

    Enrichment

    Avery, Dev, Hana, Kira

    Fluent on their level. Move them up, or give them equal fractions and decimals early.
