This is a set of resources to introduce and cover numbers from 1 – 100. There is a lengthy PowerPoint (76 slides) that covers initially 1 – 10 and then 11 – 20, followed by lots of practice activities. The numbers up to 100 are then introduced in stages. The PowerPoint has a whole range of activities, which are accompanied by a 6-page worksheet, a word search sheet and a Sudoku sheet. The activities include sums, number patterns and sequences, match-ups, true/false activities and oral practice. A great way to introduce numbers and build up to some challenging activities; ensuring the comprehension and use of all numbers up to 100.
