Fun, popular and differentiated 4 in a row board games and a Tarsia jigsaw puzzle (in PDF) for consolidating understanding of place value in decimals (1, 2 and 3 decimal places). Originally designed for Key Stage 2 (KS2) - Year 5 / 6 (P6 / P7).
FOUR IN A ROW:
• Two sets of 54 decimal number cards featuring numbers from 0.001 to 2.01 (1 set includes numbers up to 2 decimal places, the other up to 3 decimal places)
• Two A3 Four in a Row boards. The 1 star version was originally designed to go with the cards to 2 decimal places, while the more challenging 2 star version was designed for the cards to 3 decimal places. However, both sets of cards would work with either board. It works especially well in A3, however, you could scale down the board and cards should you not have the ability to print in A3. Alternatively, use the A4 Three in a Row boards which are also included.
You could have pairs take on other pairs. Each team of two starts with a set of cards (print each set on different coloured card or paper and then laminate). It works well if each team shuffles their cards, puts them in a pile and takes one from the top at a time, which they then put down on the board if there's a suitable empty box. They aim to get four of their cards in a row (or 3 if using the smaller boards). Each box has a stipulation about the numbers that can be placed on it (no tenths, < 1.5, > 0.31, < 0.56, five hundredths etc). To save printing you could split a set between 2 or 3 boards as a single team won't require all 54 cards.
The cards can also be used separately from the game boards for ordering activities. Cards and boards are editable should you want to make changes to better suit the needs of your pupils.
Print and laminate the big puzzle pieces. It features addition of decimal numbers, tenths, hundredths etc. The calculations and answers are designed to be similar so pupils have to think carefully about which answer matches which calculation. Once assembled it makes a larger triangle. A solution is included in a separate file.
