Introduction

In this numbers crossword activity, students complete a number crossword by doing sums.

Procedure

Begin the activity by writing some simple add and subtract sums on the board. Go through the sums and elicit the words plus and minus. Then, elicit the answers from the class.

Tell the students that they are going to complete a number crossword by doing sums to practice numbers one to twenty and their spelling.

Divide the students into pairs (Student A and B).

Give each student a corresponding worksheet.

Have the pairs of students sit face to face and tell them not to show their crosswords to each other.

Explain that both students have the same crossword, but Student A has the words across and Student B has the words down. Their task is to ask their partner for clues and complete sums to work out the missing numbers on their crossword and spell the numbers correctly.

Students then take it in turns to ask their partner for a clue to one of the missing numbers on their crossword, e.g. 'What's 1 down?'

Their partner then reads the sum that corresponds to that number on their worksheet.

The other student does the sum to find out the number.

When the student has the answer, they spell the number.

If the spelling is correct, the student writes the number on their crossword. If not, the student must try to spell the number again until they get it right.

To make it more challenging all the sums use the same numbers that appear on the student's own worksheet.

When the students have finished, they compare their answers.
