Students discuss making an interval estimate in multiplication problems (i.e., getting a lower and an upper limit for the actual answer using the front-end and rounding-up estimation methods). They then use this method on two problems.
Students identify fractions that are greater than a half and explain their reasoning. They also identify how far from half some fractions are and name a fraction closer to half than one given.
Students convert heights of a building into the percentage of the given total height, explaining how they solved some conversions. Assessment focus is on how they calculate these heights and what strategies they use.
Using multi-link cubes students construct and explore a growing sequence of step models, then they apply this information to continue the pattern without the cubes.
Students use place value rods in this practical task to build up square patterns. Students then predict the number needed for the next pattern and explain their rule.
