To complete the sentences, we need to use the appropriate words from the given options: grass, tree, flower, and slide. Let's look at each sentence and find the best word to fill in the blanks:
Dad is under the tree.
The word used here, 'tree,' is correct as it is logical for someone to be under a tree, perhaps for shade or rest.
Mum is on the slide.
'Slide' fits here best, as a person can be 'on' a slide. This might refer to an activity where the family is at a park or playground.
My brother is on the grass.
It makes sense for someone to sit or lie on the 'grass,' especially in a park or garden setting.
The bee is on the flower.
Bees are often found on flowers as they collect pollen, making 'flower' the logical choice.
The frisbee is in the tree.
'Tree' fits because a frisbee can get stuck 'in' a tree while playing.
Filling in the blanks correctly provides a more vivid picture of where each person or object is located, consistent with everyday experiences and logic.
