What is inside

• Three levels with eight pupil pages each, plus a how-to page: 25 pupil pages and about 248 questions in large print.
• One star, Easier (Year 1): number bonds to 10, with ten frames.
• Two stars, Core (Years 1 to 2): number bonds to 20.
• Three stars, Challenge (Years 2 to 3): number bonds to 100, first in tens and then in fives and other numbers.
• Page types at every level: missing numbers, missing numbers anywhere in the sentence, part-whole circles, ten frames (Easier) or a bond table (Core and Challenge), join the pairs, fact families, take away, and word problems.
• Full answer key and teacher notes.

Year groups and use

Years 1 to 3 (KS1 and lower KS2, ages 5 to 8). Use as a daily starter, table-time activity or homework. Counters, a number line or a ten frame can help.

Checked

Every answer is asserted by a program (a + b = total, total take away a = b, total take away b = a). Ten frames, part-whole circles and fact triangles are drawn from the same numbers as the answer key, and every join-the-pairs page has exactly one partner for each number.

Please note

Practice only: it supports teaching and does not replace it.
