Three pages of partitioning practice for Year 3 maths. Pupils warm up recombining sums like 100 + 20 + 3, move on to digit values and missing parts, then race the clock with non-standard partitions such as 200 + 130 and 15 tens. A full answer key sits at the back. Covers the England National Curriculum place value objective for three-digit numbers.
Number — number and place value
“Recognise the place value of each digit in a three-digit number (hundreds, tens, ones)”
Partitioning and recombining runs through all three levels.
Number — number and place value
“Identify, represent and estimate numbers using different representations”
Non-standard partitions like 15 tens push beyond the standard column view.
Recombine sums like 100 + 20 + 3 and complete partitions such as 245 = 200 + 40 + ___.
Give the value of marked digits and fill gaps like ___ + 50 + 2 = 152.
Non-standard partitions such as 200 + 130, 15 tens and 4 hundreds + 12 tens.
Every solution shown in bold.
