One of my most popular resources: 6 Place Value Crossnumber Puzzles, originally designed for Key Stage 2 (Year 3, 4, 5 and 6) and equivalents. This would be a good back to school activity for your new class in the first week back. There are 2 puzzles for numbers up to 5 digits / ten thousands, 2 puzzles for numbers up to 6 digits / one hundred thousands, and 2 puzzles for numbers up to 7 digits / millions. For each of 5, 6 and 7-digit numbers the first puzzle is for practising reading the word version and writing the digit version in the grid, while the second, more challenging puzzle for each involves adding and subtracting from large numbers (increase by 1000, take away five hundred thousand etc). These more challenging place value mental maths puzzles use a mixture of words and digits for the given calculations, with pupils entering digits in the grid as before. SOLUTIONS for all puzzles are provided in the same file.
These Numeracy puzzles are a more engaging alternative to worksheets and should help pupils consolidate their understanding of place value in a fun way. This pack also provides good differentation and could also be used across different age groups / classes.
You can get these puzzles alongside my other Place Value activities and games (large differentiated sets of self-check Place Value trails for 5, 6 and 7-digit numbers and also decimals Place Value games) in this good value bundle: KS2 Place Value Activities Bundle
