Frequently asked questions

▸What is place value in Grade 1?

It is the understanding that the position of a digit tells you its size. In 47, the 4 means four tens (forty) and the 7 means seven ones. Grade 1 work stays with two-digit numbers and the tens and ones places only.

▸Which place value sheets does Grade 1 have?

Six, each printed separately. Tens and Ones asks how many tens or ones are in a two-digit number. Build a Number gives the tens and ones and asks for the number they make. Expanded Form writes 45 as 40 + 5 and back again. Number Words moves between 45 and forty-five. Comparing Numbers puts two numbers side by side, and Ordering Numbers sorts three. Every sheet carries its own three levels, so the level control changes the difficulty of the skill you are on rather than switching to a different skill.

▸How do I help a child who says 47 is "four and seven"?

Build 47 with objects grouped in tens — straws, cubes or coins — so the four groups are visible. Then point at each digit and name it aloud: four tens, seven ones. Return to the Tens and Ones sheet once the grouping is clear.

▸How many questions should a Grade 1 worksheet have?

Eight to twelve keeps attention and still gives useful practice. Use the count stepper to size the sheet, and press Shuffle for a brand new set at the same level tomorrow rather than reusing the marked one.
