Student worksheet 
Answer key Amount, numeral and word
Four drawn amounts with their numerals and names in a jumble to join up, so children link the three ways of saying a number.
Which has more and closer to…
Two groups that differ enough to see without counting, and a number line without numbers with a dot to decide which end it is closer to.
Number bonds
Ten frames with full and empty counters and a part-part-whole diagram: 3 and 2 make 5, 7 and 3 make 10, 10 and 4 make 14.
Frequently asked questions about number sense
Which ages are they for?
Ages 4 to 7, in three ranges: to 5 (Nursery and Reception), to 10 (Reception and Year 1) and to 20 (Years 1 and 2). Counting objects is in the counting worksheets and comparing numbers in comparing numbers.
Are they suitable for children who find numbers hard?
They are practice material like the worksheets used in support sessions. They do not assess or diagnose anything. There is more in the learning support worksheets.
How do I use the at-a-glance cards?
Cut them out and show each one for a second or two: the child says the number without counting. Then they can write it in the box on the sheet.
Is there an answer key?
Yes: the number on each card, the joining lines, the circled group, the missing parts and the closer end.
