From: Teachers’ use of classroom assessment techniques in primary mathematics education—an explorative study with six Chinese teachers

Title

Format

Purpose

Connecting division to multiplication

Red/green cards

Assessing whether students can find the related multiplication problem for a division problem

Family problems

Red/green cards

Assessing whether students can recognize analogous problems and are aware of the relationship among the results of these problems

Choosing an answer for a division problem

Red/green cards

Assessing whether students can estimate the quotient

Identifying the watershed

Red/green cards

Assessing whether students can recognize the breaking point when the number of digits of the quotient changes

Checking divisibility

Red/green cards

Assessing whether students have a clue in advance whether divisions have a remainder or not

Is it in the hundreds/tens?

Red/green cards

Assessing whether students can estimate the quotient

Algorithm with ink blots

Worksheet

Assessing whether students understand how the division algorithm works

Is there a zero in the middle of the quotient?

Red/green cards

Assessing whether students understand the relationship between the existence of zero in the dividend and in the quotient

Correct or not correct?

Red/green cards

Assessing whether students can quickly check the correctness of the result of division problems without performing the algorithm

Is it in the multiplication table of …?

Red/green cards

Assessing whether students have the multiplication number facts available

Possible remainders

Red/green cards

Assessing whether students understand the relationship between divisors and remainders

Easy or difficult?

Worksheet

Assessing what is the easiness-difficulty range of students and whether they are aware what characteristics of a problem make it easy or difficult for them

Solving division problems without using the algorithm

Worksheet

Assessing whether students have a deep understanding of the division operation and whether they have, instead of the algorithm, other strategies available to solve division problems
