Counting up by multiples, such as 5, 10, 15, 20, is an important maths skill for kids to master.
Turn it into fun with these Missing Numbers exercises. Children count up by a number in order to identify which numbers in the sequence are missing. The children have fun "playing" whilst practising counting in multiples.
You decide what number to count up by, then press MAKE GAME. A window will appear with your Missing Numbers exercise on it for you to print.
You can specify whether blanks are to appear in the sequence and whether the answers are to be printed on the page.
...parenting tip of the moment
Infants are also, I've discovered, quite fond of the "peekaboo" game. The game is simple: Show them your face, then take it away. It's essentially two components: "I'm here," and "then I'm not." "I'm suddenly right in front of you, then mysteriously, not-so-much."...And while you're not there, they enjoy the anticipation of you coming right back in two seconds. (The first four hundred times you do it gives them a sense of the pattern.)

Small children should be supervised by a caregiver when at a computer,
to ensure no accidents occur that could hurt the child and that no equipment gets broken.
