Full Grade 4 test

The sign < means “less than”, so the boundary number itself is not allowed.

The greatest integer below a given integer is one less. Subtract 1 from the boundary. For example, for x < 12, the greatest integer allowed is 11.

“Younger than” means the age must be below the stated limit. The limit age itself is not allowed.

Subtract 1 from the limit to find the greatest whole-number age allowed. For example, someone younger than 16 can be at most 15 in whole years.

Find the missing addend by subtracting the known addend from the total.

For example, for 240 + ? = 560, the missing amount is 560 − 240 = 320. Check that the known and found addends make the given total.

After every quotient digit: multiply, subtract, and bring down the next digit. Check the final quotient by multiplication.

Every row contains the same number of tiles. Multiply the tiles in one row by the number of rows.

For example, 4 rows of 6 tiles contain 4 × 6 = 24 tiles. Include the tiles inside the rectangle too.

Count the A sectors and all sectors. The probability is the number of A sectors divided by the total number of sectors. Simplify the fraction if possible.

Set aside the travel money. Divide the remainder by the unit price and count only whole items.

Starting with the first term, repeatedly add the stated step. Compare each expected term with the displayed term in that position.

1 h = 60 min. Multiply the hours by 60 and add the remaining minutes. Hours do not convert to minutes by multiplying by 100.

Add both prices and subtract their sum from the money available.

Subtract the stated fraction from the last term. Exchange one whole for fractional parts if needed.

Find the total by multiplying the mean by the number of pupils. A mean does not mean everyone has the same result.

A square has four straight sides of equal length and four right angles.

Increasing a number by a percentage means adding the calculated increase to the original number.

1. Divide the original number by 100 and multiply by the percentage.
2. Add that increase to the original number.

For example, increasing 200 by 10% gives 200 + 20 = 220.

An acute angle is less than 90°, a right angle is 90°, and an obtuse angle is greater than 90° but less than 180°.

Use the unit shown beside the sides: mm, cm, m or km. Perimeter is a length, so it uses that same unit; area counts square units, so it is written with ².

Divide the command sequence into matching blocks. Count the blocks, not individual arrows.

When the denominators are the same, subtract the second numerator from the first. Keep the denominator unchanged.

For example, 6/9 − 2/9 = 4/9. You are subtracting equal-sized parts, so do not subtract the denominators.
