Daniel has 28 toy windmills. Elizabeth has 25 toy windmills. Pick away to model how many windmills Daniel has. Pick away to model how many windmills Elizabeth has.

The question tells us that Daniel has 28 windmills and Elizabeth has 25. First, we’re asked to pick a model, which shows how many windmills that Daniel has. We already know that Daniel has 28 windmills. But which model shows this? We can use a place value chart to show that 28 has two tens and eight ones. Both of these models showed two tens frames. So we need to compare the ones. We’re looking for the model which shows eight ones because 28 has eight ones. The first model has seven ones. The second model has eight ones. So this is the model which shows that Daniel has 28 windmills. It has 28 counters. Two 10 frames, or two tens, makes 20 and eight more makes 28.

We know that Elizabeth’s number is 25. She has 25 windmills. Which of the two models shows the number 25? Both of these models show two 10 frames. Two lots of 10 is 20. And we know the number 25 is two tens or 20 plus five. This 10 frame has four counters. So this model shows the number 24. 20 and four more makes 24. The second model has five ones. 20 and five more makes 25. This is how many windmills Elizabeth has. So this is the model that shows how many windmills Elizabeth has.
