Greater Than

This is a whole class activity.

The teacher has a set of six cards numbered 1 to 6.
They are placed face down on the teachers desk so that the teacher can pick up one at random.

Students copy the diagram (below) showing the positioning of digits in their answer. As the teacher selects a digit the students have to choose in which cell they will write it. They cannot change their mind after they have written the digit in a cell.

Game 1

Square  Square Greater Than Square  Square

Students are successful if the two digit number on the left is greater than the two digit number on the right.

If the student is successful he/she scores the two digit number on the right.

Game 2

The teacher has a set of six cards numbered 1 to 6 but this time when a number has been called out, that card goes back into the pack so it may be chosen again

Square  Square Greater Than Square  Square

Students are successful if the two digit number on the left is greater than the two digit number on the right.

If the student is successful he/she scores the two digit number on the right.

Game 3

Same as game 2 but this time the cards are numbered 1 to 9

Square  Square Greater Than Square  Square

Students are successful if the two digit number on the left is greater than the two digit number on the right.

If the student is successful he/she scores the two digit number on the right.

Game 4

Same as game 2 but this time the cards are numbered 1 to 9

Square  Square  Square  Greater Than Square  Square  Square

Students are successful if the three digit number on the left is greater than the three digit number on the right.
