WISSNER® Dienes Material Class Set (184 Pieces) made from RE-Plastic® – Base Ten System for Primary School

I am a primary teacher/tutor. I have used various brands in the past in the different schools I have worked in. I bought these for the students I tutor and am really happy with them. They are a little smaller than some brands but not much. I love that they fit together a bit like lego as it can really help children to visualise how many ones are in ten.

Good for understanding tens and units, but the small yellow blocks (ones) easily fall off the green and blue ones which make myself and my kid frustrated to put them back on and on

Could not have got maths done during lockdown. Help a great deal. If your kids are in year 1-3 get these. It will cut the stress out.
