Today's Lesson

Main Activity

For mental warm ups, please see yesterday’s lesson plan.

Turn to page 29 in Abacus 4 Textbook 3.

Remind your student of how function machines work. Once your child shows a good understanding of what is involved, ask them to copy and complete the calculations on the page.

Challenge your student to consider how they will find the missing number if it is on the left of the machine. Prompt them to think about how using division (the inverse/opposite of multiplication) will help them with the first two machines. For the final machine, the first missing number will require multiplication.

Point out the operation symbols, so your student does not accidentally do the incorrect calculation for the final function machine.
