Use patterns to practice basic addition; pupils count by two, starting from eight and counting on to 20. They record the five numbers missing from the sequence. Below, the worksheet walks learners through the process they use to count by twos, writing out all the addition number sentences they must include. Next, learners count by five from 44 to 74. Again, the answer is provided here, but this time there is space below where learners could write the equations. Consider projecting this as a whole-class problem, revealing the answers only after the class has explained their processing.
