Get Ready for fun in Grade 3!


Let's start Week 8Well done! Your child has now comprehensively revised Grade 2 mathematical knowledge and skills.By the end of this week your child will have revised all of the Grade 2 content in the Mathseeds Get Ready for Grade 3 summer school program. They should now know:

• Numbers to 100 including ordinal numbers• Counting by 10s, 5s, 2s• Fractions – halves and fourths • Adding, doubles, near doubles, bridging tens, subtracting, number fact families,

and trading • Sharing and grouping• 2D shapes and composing shapes • 3D shapes and their attributes including prisms• Basic position concepts including turns• Measuring area, mass, length and capacity with informal units • O’clock and half-past times, including digital time• Making amounts of money and calculating change• Tallies, tables, picture graphs, and basic chance terms

If you would like some data on how your child has progressed through the online content, head to the family dashboard. Choose the Mathseeds tab to see how many lessons your child has completed, where they started and where they are up to now. You can also get an overview of the number of quizzes taken and your child’s average quiz score.

This page also shows how many certificates they have earned (go to the Awards section on your child’s Mathseeds home page to print these). Plus you can see how much work they have done in the Driving Tests section. Hopefully your child has completed most of these fun little quizzes at the Grade 2 level by now.

The next step in the Mathseeds summer math program is to extend your child’s mathematical knowledge and skills to give them a head start going into Grade 3. Over the next few weeks we’re going to expand on their number knowledge, teach them some more problem solving strategies, introduce the times tables, show them some more geometry concepts, and introduce a formal length unit.

This booklet is the eighth of ten weekly booklets you will receive over the summer break. The Mathseeds summer catch up program provides a great way to make sure that your child knows the essentials they need to make a successful transition into Grade 3. We know your child will enjoy learning on Mathseeds because Mathseeds makes learning fun – and that’s what summer is all about!
