This is a series of lesson plans for Grade 3/4 maths. It can be modified up or down with some careful thinking. The students will make their own gold nugget using a bottle of up to 2 Litres filled with a material of their choice (water, dirt, stones, sand etc). They then complete 5 activities including looking at the weight, length and cost of the gold nugget. Each lesson plan is full of detail with pictures to show how to complete some activities.
